It actually\nimplements the tracking of the number of writers to a mount.\nHowever, it causes scalability problems because there can be\nhundreds of cpus doing open()/close() on files on the same mnt at\nthe same time. Even an atomic_t in the mnt has massive scalaing\nproblems because the cacheline gets so terribly contended.\n\nThis uses a statically-allocated percpu variable. All want/drop\noperations are local to a cpu as long that cpu operates on the same\nmount, and there are no writer count imbalances. Writer count\nimbalances happen when a write is taken on one cpu, and released\non another, like when an open/close pair is performed on two\n\nUpon a remount,ro request, all of the data from the percpu\nvariables is collected (expensive, but very rare) and we determine\nif there are any outstanding writers to the mount.\n\nI\u0027ve written a little benchmark to sit in a loop for a couple of\nseconds in several cpus in parallel doing open/write/close loops.\n\nhttp://sr71.net/~dave/linux/openbench.c\n\nThe code in here is a a worst-possible case for this patch. It\ndoes opens on a _pair_ of files in two different mounts in parallel.\nThis should cause my code to lose its \"operate on the same mount\"\noptimization completely. This worst-case scenario causes a 3%\ndegredation in the benchmark.\n\nI could probably get rid of even this 3%, but it would be more\ncomplex than what I have here, and I think this is getting into\nacceptable territory. In practice, I expect writing more than 3\nbytes to a file, as well as disk I/O to mask any effects that this\nhas.\n\n(To get rid of that 3%, we could have an #defined number of mounts\nin the percpu variable.

Semantics:\n\n - when the last normal reference is dropped, all special ones are\n converted to normal ones and if there had been any, cleanup is done.\n - normal reference can be cloned into a special one\n - special reference can be converted to normal one; that\u0027s a no-op if\n we\u0027d already passed the point of no return (i.e. mntput() had\n converted special references to normal and started cleanup).\n\nThe way it works: e.g. starting process accounting converts the vfsmount\nreference pinned by the opened file into special one and turns it back\nto normal when it gets shut down; acct_auto_close() is done when no\nnormal references are left. That way it does *not* obstruct umount(2)\nand it silently gets turned off when the last normal reference to\nvfsmount is gone. Which is exactly what we want...\n\nThe same should be done by LSM module that holds some internal\nreferences to vfsmount and wants to shut them down on umount - it should\nmake them special and security_sb_umount_close() will be called exactly\nwhen the last normal reference to vfsmount is gone.\n\nquota handling is even simpler - we don\u0027t use normal file IO anymore, so\nthere\u0027s no need to hold vfsmounts at all. DQUOT_OFF() is done from\ndeactivate_super(), where it really belongs.\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d53d9f16ea95a91ad4aa114809dcde486ca4000d", "tree": "f9cacb8d23e209653c6af2d30791ee93593ceda3", "parents": [ "22a4427972af371fddb49c0184a93851ad51070d" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Tue Jul 12 13:58:07 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jul 12 16:00:58 2005 -0700" }, "message": "[PATCH] name_to_dev_t warning fix\n\nkernel/power/disk.c needs a declaration of name_to_dev_t() in scope. mount.h\nseems like an appropriate choice.\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "751c404b8f63e8199d5f2f8f2bcfd69b41d11caa", "tree": "d69c76ceadbaa6f5ca3fd7be881201e87ef93377", "parents": [ "55e700b924f9e0ba24e3a071d1097d050b05abe6" ], "author": { "name": "Miklos Szeredi", "email": "miklos@szeredi.hu", "time": "Thu Jul 07 17:57:30 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Jul 07 18:23:52 2005 -0700" }, "message": "[PATCH] namespace: rename _mntput to mntput_no_expire\n\nThis patch renames _mntput() to something a little more descriptive:\nmntput_no_expire().\n\nSigned-off-by: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\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": "55e700b924f9e0ba24e3a071d1097d050b05abe6", "tree": "36a5d2401211c8fe27f6210c6fddb6db699b8015", "parents": [ "732dbef606f22a23cb3e1029d613977ec645e8ae" ], "author": { "name": "Miklos Szeredi", "email": "miklos@szeredi.hu", "time": "Thu Jul 07 17:57:30 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Jul 07 18:23:52 2005 -0700" }, "message": "[PATCH] namespace: rename mnt_fslink to mnt_expire\n\nThis patch renames vfsmount-\u003emnt_fslink to something a little more\ndescriptive: vfsmount-\u003emnt_expire.\n\nSigned-off-by: Mike Waychison \u003cmichael.waychison@sun.com\u003e\nSigned-off-by: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\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": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
