For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing. In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n pointer argument and return an integer, so most filesystems have to change\n very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n normally call simple_set_mnt() to instantiate the vfsmount. This will\n always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n dcache upon superblock destruction rather than shrink_dcache_anon().\n\n This is required because the superblock may now have multiple trees that\n aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n currently called functions assume that the whole tree is rooted at s_root,\n and that anonymous dentries are not the roots of trees which results in\n dentries being left unculled.\n\n However, with the way NFS superblock sharing are currently set to be\n implemented, these assumptions are violated: the root of the filesystem is\n simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n with child trees.\n\n [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c89681ed7d0e4a61d35bdc12c06c6733b718b2cb", "tree": "170d7c54d578480ba231dd690243aa21067ca253", "parents": [ "09d967c6f32b35eab15b45862ae16e4f06259d8e" ], "author": { "name": "Miklos Szeredi", "email": "miklos@szeredi.hu", "time": "Thu Jun 22 14:47:22 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Jun 22 15:05:57 2006 -0700" }, "message": "[PATCH] remove steal_locks()\n\nThis patch removes the steal_locks() function.\n\nsteal_locks() doesn\u0027t work correctly with any filesystem that does it\u0027s own\nlock management, including NFS, CIFS, etc.\n\nIn addition it has weird semantics on local filesystems in case tasks\nsharing file-descriptor tables are doing POSIX locking operations in\nparallel to execve().\n\nThe steal_locks() function has an effect on applications doing:\n\nclone(CLONE_FILES)\n /* in child */\n lock\n execve\n lock\n\nPOSIX locks acquired before execve (by \"child\", \"parent\" or any further\ntask sharing files_struct) will after the execve be owned exclusively by\n\"child\".\n\nAccording to Chris Wright some LSB/LTP kind of suite triggers without the\nstealing behavior, but there\u0027s no known real-world application that would\nalso fail.\n\nApps using NPTL are not affected, since all other threads are killed before\nexecve.\n\nApps using LinuxThreads are only affected if they\n\n -

Things which would require two or three syscalls with\n fadvise() can be done in a single syscall.\n\n- Using fadvise() in this manner is something not covered by POSIX.\n\nThe patch wires up the syscall for x86.\n\nThe sycall is implemented in the new fs/sync.c. The intention is that we can\nmove sys_fsync(), sys_fdatasync() and perhaps sys_sync() into there later.\n\nDocumentation for the syscall is in fs/sync.c.\n\nA test app (sync_file_range.c) is in\nhttp://www.zip.com.au/~akpm/linux/patches/stuff/ext3-tools.tar.gz.\n\nThe available-to-GPL-modules do_sync_file_range() is for knfsd: \"A COMMIT can\nsay NFS_DATA_SYNC or NFS_FILE_SYNC. I can skip the -\u003efsync call for\nNFS_DATA_SYNC which is hopefully the more common.\"\n\nNote: the `async\u0027 writeout mode SYNC_FILE_RANGE_WRITE will turn synchronous if\nthe queue is congested.

It makes such attempts appear to\nsucceed, for best 32-bit/64-bit compatibility.

Generally, all these byterange and pagerange functions are\ninclusive so we can easily represent EOF with -1.\n\nAs Ulrich notes, these two functions are somewhat abusive of the fadvise()\nconcept, which appears to be \"set the future policy for this fd\".\n\nBut these commands are a perfect fit with the fadvise() impementation, and\nseveral of the existing fadvise() commands are synchronous and don\u0027t affect\nfuture policy either. I think we can live with the slight incongruity.\n\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9b04c997b1120feefa1e6ee8e2902270bc055cd2", "tree": "09376b68d11ccce2a1ef53bac25a41a763ad36d0", "parents": [ "6961ec8267d08e21011457b05d2263ec06bdcfe1" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Fri Mar 24 03:15:10 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Mar 24 07:33:15 2006 -0800" }, "message": "[PATCH] vfs: MS_VERBOSE should be MS_SILENT\n\nThe meaning of MS_VERBOSE is backwards; if the bit is set, it really means,\n\"don\u0027t be verbose\".

Current\nimplementation supports only shmfs/tmpfs and other filesystems return\n-ENOSYS.\n\n\"Some app allocates large tmpfs files, then when some task quits and some\nclient disconnect, some memory can be released. However the only way to\nrelease tmpfs-swap is to MADV_REMOVE\". - Andrea Arcangeli\n\nDatabases want to use this feature to drop a section of their bufferpool\n(shared memory segments) - without writing back to disk/swap space.\n\nThis feature is also useful for supporting hot-plug memory on UML.\n\nConcerns raised by Andrew Morton:\n\n- \"We have no plan for holepunching! If we _do_ have such a plan (or\n might in the future) then what would the API look like? I think\n sys_holepunch(fd, start, len), so we should start out with that.\"\n\n- Using madvise is very weird, because people will ask \"why do I need to\n mmap my file before I can stick a hole in it?\"\n\n- None of the other madvise operations call into the filesystem in this\n manner. A broad question is: is this capability an MM operation or a\n filesytem operation? truncate, for example, is a filesystem operation\n which sometimes has MM side-effects. madvise is an mm operation and with\n this patch, it gains FS side-effects, only they\u0027re really, really\n significant ones.\"\n\nComments:\n\n- Andrea suggested the fs operation too but then it\u0027s more efficient to\n have it as a mm operation with fs side effects, because they don\u0027t\n immediatly know fd and physical offset of the range. It\u0027s possible to\n fixup in userland and to use the fs operation but it\u0027s more expensive,\n the vmas are already in the kernel and we can use them.\n\nShort term plan \u0026 Future Direction:\n\n- We seem to need this interface only for shmfs/tmpfs files in the short\n term. We have to add hooks into the filesystem for correctness and\n completeness. This is what this patch does.\n\n- In the future, plan is to support both fs and mmap apis also. This\n also involves (other) filesystem specific functions to be implemented.\n\n- Current patch doesn\u0027t support VM_NONLINEAR - which can be addressed in\n the future.\n\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Andrea Arcangeli \u003candrea@suse.de\u003e\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "994fc28c7b1e697ac56befe4aecabf23f0689f46", "tree": "da36d162e9bd077e9b5be385b28e2db90475c263", "parents": [ "7063fbf2261194f72ee75afca67b3b38b554b5fa" ], "author": { "name": "Zach Brown", "email": "zach.brown@oracle.com", "time": "Thu Dec 15 14:28:17 2005 -0800" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Tue Jan 03 11:45:42 2006 -0800" }, "message": "[PATCH] add AOP_TRUNCATED_PAGE, prepend AOP_ to WRITEPAGE_ACTIVATE\n\nreadpage(), prepare_write(), and commit_write() callers are updated to\nunderstand the special return code AOP_TRUNCATED_PAGE in the style of\nwritepage() and WRITEPAGE_ACTIVATE.

A\nglobal list of fdtable to be freed is not scalable, so we use a per-cpu list.\nIf keventd is already handling the current cpu\u0027s work, we use a timer to defer\nqueueing of that work.\n\nSince the last publication, this patch has been re-written to avoid using\nexplicit memory barriers and use rcu_assign_pointer(), rcu_dereference()\npremitives instead. This required that the fd information is kept in a\nseparate structure (fdtable) and updated atomically.\n\nSigned-off-by: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a7662236253374012d364106b6dc9161bd929e2e", "tree": "59f34811d18fef8195bc3200bdb2684598175f29", "parents": [ "e6c9f5c1888097c936334bf9740024520ca47b8e" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Tue Sep 06 15:19:10 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 16:57:55 2005 -0700" }, "message": "[PATCH] Make ll_rw_block() wait for buffer lock\n\nIntroduce new ll_rw_block() operation SWRITE meaning that block layer should\nwait for the buffer lock and write-out afterwards.

A\nmultithreaded application could close a file descriptor at the same time as\nit is trying to acquire a lock using the same file descriptor. I would\nsuggest that that multithreaded application is not providing the proper\nsynchronization for itself, but the OS should still behave correctly.\n\nSUS3 (Single UNIX Specification Version 3, read: POSIX) indicates that when\na file descriptor is closed, that all POSIX locks on the file, owned by the\nprocess which closed the file descriptor, should be released.\n\nThe trick here is when those locks are released. The current code releases\nall locks which exist when close is processing, but any locks in progress\nare handled when the last reference to the open file is released.\n\nThere are three cases to consider.\n\nOne is the simple case, a multithreaded (mt) process has a file open and\nraces to close it and acquire a lock on it. In this case, the close will\nrelease one reference to the open file and when the fcntl is done, it will\nrelease the other reference. For this situation, no locks should exist on\nthe file when both the close and fcntl operations are done. The current\nsystem will handle this case because the last reference to the open file is\nbeing released.\n\nThe second case is when the mt process has dup(2)\u0027d the file descriptor.\nThe close will release one reference to the file and the fcntl, when done,\nwill release another, but there will still be at least one more reference\nto the open file. One could argue that the existence of a lock on the file\nafter the close has completed is okay, because it was acquired after the\nclose operation and there is still a way for the application to release the\nlock on the file, using an existing file descriptor.\n\nThe third case is when the mt process has forked, after opening the file\nand either before or after becoming an mt process. In this case, each\nprocess would hold a reference to the open file. For each process, this\ndegenerates to first case above. However, the lock continues to exist\nuntil both processes have released their references to the open file. This\nlock could block other lock requests.\n\nThe changes to release the lock when the last reference to the open file\naren\u0027t quite right because they would allow the lock to exist as long as\nthere was a reference to the open file. This is too long.\n\nThe new proposed solution is to add support in the fcntl code path to\ndetect a race with close and then to release the lock which was just\nacquired when such as race is detected. This causes locks to be released\nin a timely fashion and for the system to conform to the POSIX semantic\nspecification.\n\nThis was tested by instrumenting a kernel to detect the handling locks and\nthen running a program which generates case #3 above. A dangling lock\ncould be reliably generated. When the changes to detect the close/fcntl\nrace were added, a dangling lock could no longer be generated.\n\nCc: Matthew Wilcox \u003cwilly@debian.org\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "88bd5121d635136e01369141367f315665534b3c", "tree": "33de8dda3d77ebf7bf48864c464a36665f66497c", "parents": [ "9a556e89081b0c1c2f83cee915363b15a68a6f2d" ], "author": { "name": "Anton Altaparmakov", "email": "aia21@cam.ac.uk", "time": "Wed Jul 13 01:10:44 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Jul 13 11:25:24 2005 -0700" }, "message": "[PATCH] Fix soft lockup due to NTFS: VFS part and explanation\n\nSomething has changed in the core kernel such that we now get concurrent\ninode write outs, one e.g via pdflush and one via sys_sync or whatever.\nThis causes a nasty deadlock in ntfs. The only clean solution\nunfortunately requires a minor vfs api extension.\n\nFirst the deadlock analysis:\n\nPrerequisive knowledge: NTFS has a file $MFT (inode 0) loaded at mount\ntime. The NTFS driver uses the page cache for storing the file contents as\nusual. More interestingly this file contains the table of on-disk inodes\nas a sequence of MFT_RECORDs. Thus NTFS driver accesses the on-disk inodes\nby accessing the MFT_RECORDs in the page cache pages of the loaded inode\n$MFT.\n\nThe situation: VFS inode X on a mounted ntfs volume is dirty. For same\ninode X, the ntfs_inode is dirty and thus corresponding on-disk inode,\nwhich is as explained above in a dirty PAGE_CACHE_PAGE belonging to the\ntable of inodes ($MFT, inode 0).\n\nWhat happens:\n\nProcess 1: sys_sync()/umount()/whatever... calls __sync_single_inode() for\n$MFT -\u003e do_writepages() -\u003e write_page for the dirty page containing the\non-disk inode X, the page is now locked -\u003e ntfs_write_mst_block() which\nclears PageUptodate() on the page to prevent anyone else getting hold of it\nwhilst it does the write out (this is necessary as the on-disk inode needs\n\"fixups\" applied before the write to disk which are removed again after the\nwrite and PageUptodate is then set again). It then analyses the page\nlooking for dirty on-disk inodes and when it finds one it calls\nntfs_may_write_mft_record() to see if it is safe to write this on-disk\ninode. This then calls ilookup5() to check if the corresponding VFS inode\nis in icache(). This in turn calls ifind() which waits on the inode lock\nvia wait_on_inode whilst holding the global inode_lock.\n\nProcess 2: pdflush results in a call to __sync_single_inode for the same\nVFS inode X on the ntfs volume. This locks the inode (I_LOCK) then calls\nwrite-inode -\u003e ntfs_write_inode -\u003e map_mft_record() -\u003e read_cache_page() of\nthe page (in page cache of table of inodes $MFT, inode 0) containing the\non-disk inode. This page has PageUptodate() clear because of Process 1\n(see above) so read_cache_page() blocks when tries to take the page lock\nfor the page so it can call ntfs_read_page().\n\nThus Process 1 is holding the page lock on the page containing the on-disk\ninode X and it is waiting on the inode X to be unlocked in ifind() so it\ncan write the page out and then unlock the page.\n\nAnd Process 2 is holding the inode lock on inode X and is waiting for the\npage to be unlocked so it can call ntfs_readpage() or discover that\nProcess 1 set PageUptodate() again and use the page.\n\nThus we have a deadlock due to ifind() waiting on the inode lock.\n\nThe only sensible solution: NTFS does not care whether the VFS inode is\nlocked or not when it calls ilookup5() (it doesn\u0027t use the VFS inode at\nall, it just uses it to find the corresponding ntfs_inode which is of\ncourse attached to the VFS inode (both are one single struct); and it uses\nthe ntfs_inode which is subject to its own locking so I_LOCK is irrelevant)\nhence we want a modified ilookup5_nowait() which is the same as ilookup5()\nbut it does not wait on the inode lock.\n\nWithout such functionality I would have to keep my own ntfs_inode cache in\nthe NTFS driver just so I can find ntfs_inodes independent of their VFS\ninodes which would be slow, memory and cpu cycle wasting, and incredibly\nstupid given the icache already exists in the VFS.\n\nBelow is a patch that does the ilookup5_nowait() implementation in\nfs/inode.c and exports it.\n\nilookup5_nowait.diff:\n\nIntroduce ilookup5_nowait() which is basically the same as ilookup5() but\nit does not wait on the inode\u0027s lock (i.e. it omits the wait_on_inode()\ndone in ifind()).\n\nThis is needed to avoid a nasty deadlock in NTFS.\n\nSigned-off-by: Anton Altaparmakov \u003caia21@cantab.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0eeca28300df110bd6ed54b31193c83b87921443", "tree": "7db42d8a18d80eca538f5b7d25e0532b8fa38b85", "parents": [ "bd4c625c061c2a38568d0add3478f59172455159" ], "author": { "name": "Robert Love", "email": "rml@novell.com", "time": "Tue Jul 12 17:06:03 2005 -0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jul 12 20:38:38 2005 -0700" }, "message": "[PATCH] inotify\n\ninotify is intended to correct the deficiencies of dnotify, particularly\nits inability to scale and its terrible user interface:\n\n * dnotify requires the opening of one fd per each directory\n that you intend to watch.
