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.

Note:\n there is subtle difference, unbindable mounts cannot be bind mounted\n but can be cloned during clone-namespace.\n\nSigned-off-by: Ram Pai \u003clinuxram@us.ibm.com\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a58b0eb8e64b78d9315a5491955e78b1391d42e5", "tree": "546f77cb0338c817ef1e34d8ebbc6eaf0e5d6be9", "parents": [ "a05964f3917c7c55368c229d7985f8e7c9977e97" ], "author": { "name": "Ram Pai", "email": "linuxram@us.ibm.com", "time": "Mon Nov 07 17:20:48 2005 -0500" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Nov 07 18:18:11 2005 -0800" }, "message": "[PATCH] introduce slave mounts\n\nA slave mount always has a master mount from which it receives\nmount/umount events.

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.

I.e. add a new flag\n(I_FORCED_FREEING), set it before write_inode_now() there and make\nprune_icache() leave those alone.\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "8d0a8a9d0ec790086c64d210af413ac351d89e35", "tree": "003a1481e4a8d8487956a6bf04db80dd93264b8b", "parents": [ "ecdbf769b2cb8903e07cd482334c714d89fd1146" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jun 22 17:16:32 2005 +0000" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jun 22 16:07:42 2005 -0400" }, "message": "[PATCH] NFSv4: Clean up nfs4 lock state accounting\n\n Ensure that lock owner structures are not released prematurely.\n\n Signed-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "acaefc25d21f850e47ecc5098d1e0bc442c526be", "tree": "fbc7aa605c71667507b54d3b3320f9a999458dd4", "parents": [ "4109aca06cb7b042ea791d0f9d3c9615bc3bf5cd" ], "author": { "name": "Arnd Bergmann", "email": "arnd@arndb.de", "time": "Wed May 18 14:40:59 2005 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Jun 20 15:15:30 2005 -0700" }, "message": "[PATCH] libfs: add simple attribute files\n\nBased on the discussion about spufs attributes, this is my suggestion\nfor a more generic attribute file support that can be used by both\ndebugfs and spufs.\n\nSimple attribute files behave similarly to sequential files from\na kernel programmers perspective in that a standard set of file\noperations is provided and only an open operation needs to\nbe written that registers file specific get() and set() functions.\n\nThese operations are defined as\n\nvoid foo_set(void *data, u64 val); and\nu64 foo_get(void *data);\n\nwhere data is the inode-\u003eu.generic_ip pointer of the file and the\noperations just need to make send of that pointer.

The documentation could be extended for more\nsources which are equipped by structured comments for recent 2.6 kernels. I\nhave tried to proceed with that task. I have done that more times from 2.6.0\ntime and it gets boring to do same changes again and again. Linux kernel\ncompiles after changes for i386 and ARM targets. I have added references to\nsome more files into kernel-api book, I have added some section names as well.\n So please, check that changes do not break something and that categories are\nnot too much skewed.\n\nI have changed kernel-doc to accept \"fastcall\" and \"asmlinkage\" words reserved\nby kernel convention. Most of the other changes are modifications in the\ncomments to make kernel-doc happy, accept some parameters description and do\nnot bail out on errors. Changed \u003cpid\u003e to @pid in the description, moved some\n#ifdef before comments to correct function to comments bindings, etc.\n\nYou can see result of the modified documentation build at\n http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz\n\nSome more sources are ready to be included into kernel-doc generated\ndocumentation.
