We can\u0027t do anything for filesystems that have actual\n \u003e32-bit inode numbers, but on filesystems that generate i_ino values on the\n fly, we should try to have them fit in 32 bits. We could trivially fix this\n by making the static counters in new_inode and iunique 32 bits, but...\n\n- many filesystems call new_inode and assume that the i_ino values they are\n given are unique. They are not guaranteed to be so, since the static\n counter can wrap. This problem is exacerbated by the fix for #1.\n\n- after allocating a new inode, some filesystems call iunique to try to get\n a unique i_ino value, but they don\u0027t actually add their inodes to the\n hashtable, and so they\u0027re still not guaranteed to be unique if that counter\n wraps.\n\nThis patch set takes the simpler approach of simply using iunique and hashing\nthe inodes afterward. Christoph H. previously mentioned that he thought that\nthis approach may slow down lookups for filesystems that currently hash their\ninodes.\n\nThe questions are:\n\n1) how much would this slow down lookups for these filesystems?\n2) is it enough to justify adding more infrastructure to avoid it?\n\nWhat might be best is to start with this approach and then only move to using\nIDR or some other scheme if these extra inodes in the hashtable prove to be\nproblematic.\n\nI\u0027ve done some cursory testing with this patch and the overhead of hashing and\nunhashing the inodes with pipefs is pretty low -- just a few seconds of system\ntime added on to the creation and destruction of 10 million pipes (very\nsimilar to the overhead that the IDR approach would add).\n\nThe hard thing to measure is what effect this has on other filesystems. I\u0027m\nopen to ways to try and gauge this.\n\nAgain, I\u0027ve only converted pipefs as an example. If this approach is\nacceptable then I\u0027ll start work on patches to convert other filesystems.\n\nWith a pretty-much-worst-case microbenchmark provided by Eric Dumazet\n\u003cdada1@cosmosbay.com\u003e:\n\nhashing patch (pipebench):\nsys 1m15.329s\nsys 1m16.249s\nsys 1m17.169s\n\nunpatched (pipebench):\nsys 1m9.836s\nsys 1m12.541s\nsys 1m14.153s\n\nWhich works out to 1.05642174294555027017. So ~5-6% slowdown.\n\nThis patch:\n\nWhen a 32-bit program that was not compiled with large file offsets does a\nstat and gets a st_ino value back that won\u0027t fit in the 32 bit field, glibc\n(correctly) generates an EOVERFLOW error. We can\u0027t do anything about fs\u0027s\nwith larger permanent inode numbers, but when we generate them on the fly, we\nought to try and have them fit within a 32 bit field.\n\nThis patch takes the first step toward this by making the static counters in\nthese two functions be 32 bits.\n\n[jlayton@redhat.com: mention that it\u0027s only the case for 32bit, non-LFS stat]\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b5e618181a927210f8be1d3d2249d31904ba358d", "tree": "731f1ae4ff1ba56d402bb329182b7d935bb439a1", "parents": [ "db9c02fa8bd50eb104781a9f78cae923d8da1e74" ], "author": { "name": "Pavel Emelianov", "email": "xemul@sw.ru", "time": "Tue May 08 00:30:19 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:11 2007 -0700" }, "message": "Introduce a handy list_first_entry macro\n\nThere are many places in the kernel where the construction like\n\n foo \u003d list_entry(head-\u003enext, struct foo_struct, list);\n\nare used.\nThe code might look more descriptive and neat if using the macro\n\n list_first_entry(head, type, member) \\\n list_entry((head)-\u003enext, type, member)\n\nHere is the macro itself and the examples of its usage in the generic code.\n If it will turn out to be useful, I can prepare the set of patches to\ninject in into arch-specific code, drivers, networking, etc.\n\nSigned-off-by: Pavel Emelianov \u003cxemul@openvz.org\u003e\nSigned-off-by: Kirill Korotaev \u003cdev@openvz.org\u003e\nCc: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Zach Brown \u003czach.brown@oracle.com\u003e\nCc: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nCc: John McCutchan \u003cttb@tentacle.dhs.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: john stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Ram Pai \u003clinuxram@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "3361c7bebbf207f57f3dd1282cd87e1e37c082ac", "tree": "53c5ee74c70ed9727964996f3cf2fa4a0ff368ea", "parents": [ "9d0633cfedde484d30eef869f749c04709ab3e42" ], "author": { "name": "Jeffrey Layton", "email": "jlayton@redhat.com", "time": "Tue May 08 00:29:48 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:10 2007 -0700" }, "message": "make iunique use a do/while loop rather than its obscure goto loop\n\nA while back, Christoph mentioned that he thought that iunique ought to be\ncleaned up to use a more conventional loop construct.

They have no\nessential function for the VM.\n\nWe use a simple increment of per cpu variables. In order to avoid the most\nsevere races we disable preempt. Preempt does not prevent the race between\nan increment and an interrupt handler incrementing the same statistics\ncounter. However, that race is exceedingly rare, we may only loose one\nincrement or so and there is no requirement (at least not in kernel) that\nthe vm event counters have to be accurate.\n\nIn the non preempt case this results in a simple increment for each\ncounter. For many architectures this will be reduced by the compiler to a\nsingle instruction. This single instruction is atomic for i386 and x86_64.\n And therefore even the rare race condition in an interrupt is avoided for\nboth architectures in most cases.\n\nThe patchset also adds an off switch for embedded systems that allows a\nbuilding of linux kernels without these counters.\n\nThe implementation of these counters is through inline code that hopefully\nresults in only a single instruction increment instruction being emitted\n(i386, x86_64) or in the increment being hidden though instruction\nconcurrency (EPIC architectures such as ia64 can get that done).\n\nBenefits:\n- VM event counter operations usually reduce to a single inline instruction\n on i386 and x86_64.\n- No interrupt disable, only preempt disable for the preempt case.\n Preempt disable can also be avoided by moving the counter into a spinlock.\n- Handling is similar to zoned VM counters.\n- Simple and easily extendable.\n- Can be omitted to reduce memory use for embedded use.\n\nReferences:\n\nRFC http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113512330605497\u0026w\u003d2\nRFC http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d114988082814934\u0026w\u003d2\nlocal_t http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d114991748606690\u0026w\u003d2\nV2 http://marc.theaimsgroup.com/?t\u003d115014808400007\u0026r\u003d1\u0026w\u003d2\nV3 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d115024767022346\u0026w\u003d2\nV4 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d115047968808926\u0026w\u003d2\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "6ab3d5624e172c553004ecc862bfeac16d9d68b7", "tree": "6d98881fe91fd9583c109208d5c27131b93fa248", "parents": [ "e02169b682bc448ccdc819dc8639ed34a23cedd8" ], "author": { "name": "Jörn Engel", "email": "joern@wohnheim.fh-wedel.de", "time": "Fri Jun 30 19:25:36 2006 +0200" }, "committer": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Fri Jun 30 19:25:36 2006 +0200" }, "message": "Remove obsolete #include \u003clinux/config.h\u003e\n\nSigned-off-by: Jörn Engel \u003cjoern@wohnheim.fh-wedel.de\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\n" }, { "commit": "f5e54d6e53a20cef45af7499e86164f0e0d16bb2", "tree": "cb92acbb89b84796261bf5563182261ec5654127", "parents": [ "a052b68b1e7a31f1e6a721290035e9deb0f6fed9" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Wed Jun 28 04:26:44 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Jun 28 14:59:04 2006 -0700" }, "message": "[PATCH] mark address_space_operations const\n\nSame as with already do with the file operations: keep them in .rodata and\nprevents people from doing runtime patching.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Steven French \u003csfrench@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b7542f8c7eb40efb967a558c5be90fe5f939c3ef", "tree": "f0df8a2eb2f9a704696bedb455a1de8e002c75e2", "parents": [ "f6298aab2ebaa61de39931595f125bc1968905cc" ], "author": { "name": "Eric Sesterhenn", "email": "snakebyte@gmx.de", "time": "Sun Apr 02 13:38:18 2006 +0200" }, "committer": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Sun Apr 02 13:38:18 2006 +0200" }, "message": "BUG_ON() Conversion in fs/inode.c\n\nthis changes if() BUG();

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.

Suppose kswapd invokes shrink_icache_memory() to free\nsome RAM. In prune_icache() inodes are removed from i_hash. prune_icache\n() is then going to call clear_inode(), but drops the inode_lock\nspinlock before this.

I remove them from i_hash under spinlock protection.\nSince the i_state is set to I_FREEING, it is safe to do this. The others\nwill sleep waiting for the inode state change.\n\nI also postpone removing inodes from i_sb_list. It is not compulsory to\ndo so but I do it for readability reasons. Inodes are added/removed to\nthe lists together everywhere in the code and there is no point to\nchange this rule. This is harmless because the only user of i_sb_list\nwhich somehow may interfere with me (invalidate_list()) is excluded by\nthe iprune_sem mutex.\n\nThe same race is possible in invalidate_list() so I do the same for it.\n\nAcked-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "168a9fd6a1bf91041adf9909f6c72cf747f0ca8c", "tree": "65b4dc843f34f0837b10f4fbbc1763f5aae87b7b", "parents": [ "3b6bfcdb116f2cc2cab921fcac6d39d4022952d2" ], "author": { "name": "Miklos Szeredi", "email": "miklos@szeredi.hu", "time": "Tue Jul 12 13:58:10 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jul 12 16:00:59 2005 -0700" }, "message": "[PATCH] __wait_on_freeing_inode fix\n\nThis patch fixes queer behavior in __wait_on_freeing_inode().\n\nIf I_LOCK was not set it called yield(), effectively busy waiting for the\nremoval of the inode from the hash.
