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": "4294621f41a85497019fae64341aa5351a1921b7", "tree": "fdeb7eb44384a99d0679ffa6de5019bab0ea2166", "parents": [ "404351e67a9facb475abf1492245374a28d13e90" ], "author": { "name": "Hugh Dickins", "email": "hugh@veritas.com", "time": "Sat Oct 29 18:16:05 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Oct 29 21:40:38 2005 -0700" }, "message": "[PATCH] mm: rss \u003d file_rss + anon_rss\n\nI was lazy when we added anon_rss, and chose to change as few places as\npossible.

The output file containing the\nprocess accounting data can grow very large if the system is large enough\nand active enough. If the 2GB limit is reached, then the system simply\nstops storing process accounting data.\n\nAnother annoying problem is that once the system reaches this 2GB limit,\nthen every process which exits will receive a signal, SIGXFSZ. This signal\nis generated because an attempt was made to write beyond the limit for the\nfile descriptor. This signal makes it look like every process has exited\ndue to a signal, when in fact, they have not.\n\nThe solution is to add the O_LARGEFILE flag to the list of flags used to\nopen the accounting file. The rest of the accounting support is already\nlargefile safe.\n\nThe changes were tested by constructing a large file (just short of 2GB),\nenabling accounting, and then running enough commands to cause the\naccounting data generated to increase the size of the file to 2GB. Without\nthe changes, the file grows to 2GB and the last command run in the test\nscript appears to exit due a signal when it has not. With the changes,\nthings work as expected and quietly.\n\nThere are some user level changes required so that it can deal with\nlargefiles, but those are being handled separately.\n\nSigned-off-by: Peter Staubach \u003cstaubach@redhat.com\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.
