Rather than\nsetattr \u003e vmtruncate \u003e truncate, have filesystems call their truncate sequence\nfrom -\u003esetattr if filesystem specific operations are required. vmtruncate is\ndeprecated, and truncate_pagecache and inode_newsize_ok helpers introduced\npreviously should be used.\n\nsimple_setattr is introduced for simple in-ram filesystems to implement\nthe new truncate sequence. Eventually all filesystems should be converted\nto implement a setattr, and the default code in notify_change should go\naway.\n\nsimple_setsize is also introduced to perform just the ATTR_SIZE portion\nof simple_setattr (ie. changing i_size and trimming pagecache).\n\nTo implement the new truncate sequence:\n- filesystem specific manipulations (eg freeing blocks) must be done in\n the setattr method rather than -\u003etruncate.\n- vmtruncate can not be used by core code to trim blocks past i_size in\n the event of write failure after allocation, so this must be performed\n in the fs code.\n- convert usage of helpers block_write_begin, nobh_write_begin,\n cont_write_begin, and *blockdev_direct_IO* to use _newtrunc postfixed\n variants. These avoid calling vmtruncate to trim blocks (see previous).\n- inode_setattr should not be used. generic_setattr is a new function\n to be used to copy simple attributes into the generic inode.\n- make use of the better opportunity to handle errors with the new sequence.\n\nBig problem with the previous calling sequence: the filesystem is not called\nuntil i_size has already changed. This means it is not allowed to fail the\ncall, and also it does not know what the previous i_size was. Also, generic\ncode calling vmtruncate to truncate allocated blocks in case of error had\nno good way to return a meaningful error (or, for example, atomically handle\nblock deallocation).\n\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nAcked-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "7ea8085910ef3dd4f3cad6845aaa2b580d39b115", "tree": "d9c1edb5906f943f7d70bfb4b65106e29772d379", "parents": [ "cc967be54710d97c05229b2e5ba2d00df84ddd64" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Wed May 26 17:53:25 2010 +0200" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu May 27 22:05:02 2010 -0400" }, "message": "drop unused dentry argument to -\u003efsync\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "866707fc2721df8fee637fcf0239628b9231f9ea", "tree": "485b1a369c1b879a2dd556e44bd30a23e6bfd87f", "parents": [ "ca572727dbb945e443564029a495157fd2e72995" ], "author": { "name": "Jan Blunck", "email": "jblunck@suse.de", "time": "Wed May 26 14:44:54 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 27 09:12:56 2010 -0700" }, "message": "Documentation/filesystems/Locking: update documentation on llseek() wrt BKL\n\nThe inode\u0027s i_size is not protected by the big kernel lock.

For x86_64, a fork will result in the task-\u003estack_start\nvalue being updated to the current user top of stack and not the stack\nstart address. This unpredictability of the stack_start value makes\nit worthless. That includes the intended use of showing how much stack\nspace a thread has.\n\nOther architectures will get different values. As an example, ia64\ngets 0. The do_fork() and copy_process() functions appear to treat the\nstack_start and stack_size parameters as architecture specific.\n\nI only partially reverted c44972f1 (\"procfs: disable per-task stack usage\non NOMMU\") . If I had completely reverted it, I would have had to change\nmm/Makefile only build pagewalk.o when CONFIG_PROC_PAGE_MONITOR is\nconfigured. Since I could not test the builds without significant effort,\nI decided to not change mm/Makefile.\n\nI only partially reverted 89240ba0 (\"x86, fs: Fix x86 procfs stack\ninformation for threads on 64-bit\") .

Should we not find free space, an existing\nreservation is pulled off the LRU and cannibalized.\n\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "a33f32244d8550da8b4a26e277ce07d5c6d158b5", "tree": "2b24b891e48ae791446fef6d1b9e520190c03c62", "parents": [ "6c9468e9eb1252eaefd94ce7f06e1be9b0b641b1" ], "author": { "name": "Francis Galiegue", "email": "fgaliegue@gmail.com", "time": "Fri Apr 23 00:08:02 2010 +0200" }, "committer": { "name": "Jiri Kosina", "email": "jkosina@suse.cz", "time": "Fri Apr 23 02:09:52 2010 +0200" }, "message": "Documentation/: it\u0027s -\u003e its where appropriate\n\nFix obvious cases of \"it\u0027s\" being used when \"its\" was meant.\n\nSigned-off-by: Francis Galiegue \u003cfgaliegue@gmail.com\u003e\nAcked-by: Randy Dunlap \u003crdunlap@xenotime.net\u003e\nSigned-off-by: Jiri Kosina \u003cjkosina@suse.cz\u003e\n" }, { "commit": "6c9468e9eb1252eaefd94ce7f06e1be9b0b641b1", "tree": "797676a336b050bfa1ef879377c07e541b9075d6", "parents": [ "4cb3ca7cd7e2cae8d1daf5345ec99a1e8502cf3f", "c81eddb0e3728661d1585fbc564449c94165cc36" ], "author": { "name": "Jiri Kosina", "email": "jkosina@suse.cz", "time": "Fri Apr 23 02:08:44 2010 +0200" }, "committer": { "name": "Jiri Kosina", "email": "jkosina@suse.cz", "time": "Fri Apr 23 02:08:44 2010 +0200" }, "message": "Merge branch \u0027master\u0027 into for-next\n" }, { "commit": "7c7145f6acc68100dbdc5d3c5c64fe3af1c99c89", "tree": "5e93e3eb4787229032f1df222fa490112f4b0c32", "parents": [ "92d6b71ab906be706f3679353b30a8d2c3831144", "0d0fb0f9c5fddef4a10242fe3337f00f528a3099" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Tue Apr 13 14:12:17 2010 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Tue Apr 13 14:12:17 2010 +0200" }, "message": "Merge branch \u0027linus\u0027 into irq/core\n\nReason: Get the upstream IRQF_DISABLED related changes.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "9208d24253e5e644f8cb1b87b69de44897668303", "tree": "130092938941e26f32428497ce9335dcebeb367d", "parents": [ "476ada0436351672fbf482db54cb94b8ba877709" ], "author": { "name": "Sripathi Kodi", "email": "sripathik@in.ibm.com", "time": "Thu Mar 18 08:01:33 2010 +0000" }, "committer": { "name": "Eric Van Hensbergen", "email": "ericvh@gmail.com", "time": "Mon Apr 05 10:37:36 2010 -0500" }, "message": "9p: documentation update\n\nThis patch adds documentation for new 9P options introduced in\n2.6.34.\n\nSigned-off-by: Sripathi Kodi \u003csripathik@in.ibm.com\u003e\nSigned-off-by: Eric Van Hensbergen \u003cericvh@gmail.com\u003e\n" }, { "commit": "9f321603724be7386ea39ea41fd885954db60a4a", "tree": "efd64c26c2fb2698ecd95c2f10dc1016b45ba4a4", "parents": [ "9d54e2c0b0a03b0f05fc4f988323c858ec9d7740", "82593f87b6c1922a8f8317bb165c6c7794fa4639" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 29 14:42:25 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 29 14:42:25 2010 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (28 commits)\n ceph: update discussion list address in MAINTAINERS\n ceph: some documentations fixes\n ceph: fix use after free on mds __unregister_request\n ceph: avoid loaded term \u0027OSD\u0027 in documention\n ceph: fix possible double-free of mds request reference\n ceph: fix session check on mds reply\n ceph: handle kmalloc() failure\n ceph: propagate mds session allocation failures to caller\n ceph: make write_begin wait propagate ERESTARTSYS\n ceph: fix snap rebuild condition\n ceph: avoid reopening osd connections when address hasn\u0027t changed\n ceph: rename r_sent_stamp r_stamp\n ceph: fix connection fault con_work reentrancy problem\n ceph: prevent dup stale messages to console for restarting mds\n ceph: fix pg pool decoding from incremental osdmap update\n ceph: fix mds sync() race with completing requests\n ceph: only release unused caps with mds requests\n ceph: clean up handle_cap_grant, handle_caps wrt session mutex\n ceph: fix session locking in handle_caps, ceph_check_caps\n ceph: drop unnecessary WARN_ON in caps migration\n ...\n" }, { "commit": "8136b58dd0fce0b4cb649ac690e0493fb6fdacdb", "tree": "7872de6b64028e7b10d6688baea9834523a4b974", "parents": [ "94aa8ae13db2ecf2ec1b4e65a65d3fe92b468e0e" ], "author": { "name": "Cheng Renquan", "email": "crquan@gmail.com", "time": "Mon Mar 29 19:05:57 2010 +0800" }, "committer": { "name": "Sage Weil", "email": "sage@newdream.net", "time": "Mon Mar 29 09:52:11 2010 -0700" }, "message": "ceph: some documentations fixes\n\nNew documentation should have an entry in the 00-INDEX.

This means that some data won\u0027t make it into the\ncache this time. To support this, a new FS-Cache function is added\nfscache_maybe_release_page() that replaces what the netfs releasepage()\nfunctions used to do with respect to the cache.\n\nThe decisions fscache_maybe_release_page() makes are counted and displayed\nthrough /proc/fs/fscache/stats on a line labelled \"VmScan\". There are four\ncounters provided: \"nos\u003dN\" - pages that weren\u0027t pending storage; \"gon\u003dN\" -\npages that were pending storage when we first looked, but weren\u0027t by the time\nwe got the object lock; \"bsy\u003dN\" - pages that we ignored as they were actively\nbeing written when we looked; and \"can\u003dN\" - pages that we cancelled the storage\nof.\n\nWhat I\u0027d really like to do is alter the behaviour of the cancellation\nheuristics, depending on how necessary it is to expel pages. If there are\nplenty of other pages that aren\u0027t waiting to be written to the cache that\ncould be ejected first, then it would be nice to hold up on immediate\ncancellation of cache writes - but I don\u0027t see a way of doing that.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "e3d4d28b1c8cc7c26536a50b43d86ccd39878550", "tree": "23f6dacd5ffdf6c6d01c411517855a41405381b9", "parents": [ "285e728b0ac55b53a673114096168d6f74930167" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Nov 19 18:11:32 2009 +0000" }, "committer": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Nov 19 18:11:32 2009 +0000" }, "message": "FS-Cache: Handle read request vs lookup, creation or other cache failure\n\nFS-Cache doesn\u0027t correctly handle the netfs requesting a read from the cache\non an object that failed or was withdrawn by the cache.
