So introduce\n-\u003eupdate_time, where we will deal with i_version an a/m/c time updates and\nindicate which changes need to be made. The normal version just does what it\nhas always done, updates the time and marks the inode dirty, and then\nfilesystems can choose to do something different.\n\nI\u0027ve gone through all of the users of file_update_time and made them check for\nerrors with the exception of the fault code since it\u0027s complicated and I wasn\u0027t\nquite sure what to do there, also Jan is going to be pushing the file time\nupdates into page_mkwrite for those who have it so that should satisfy btrfs and\nmake it not a big deal to check the file_update_time() return code in the\ngeneric fault path.

This can be passed\nat the time of open() as well as via fcntl().\n\nNote that asynchronous O_DIRECT iocb jobs are completed synchronously\nalways (this has been the case with FUSE even before this patch)\n\nSigned-off-by: Anand Avati \u003cavati@redhat.com\u003e\nReviewed-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\n" }, { "commit": "ac45d61357e86b9a0cf14e45e8e09dfb626970ef", "tree": "e560d3a8f26d1530780ed62f2a4bd3f16a20ac55", "parents": [ "192cfd58774b4d17b2fe8bdc77d89c2ef4e0591d" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Mon Mar 05 15:48:11 2012 +0100" }, "committer": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Mon Mar 05 15:48:11 2012 +0100" }, "message": "fuse: fix nlink after unlink\n\nAnand Avati reports that the following sequence of system calls fail on a fuse\nfilesystem:\n\n\n \tcreate(\"filename\") \u003d\u003e 0\n \tlink(\"filename\", \"linkname\") \u003d\u003e 0\n \tunlink(\"filename\") \u003d\u003e 0\n \tlink(\"linkname\", \"filename\") \u003d\u003e -ENOENT ### BUG ###\n\nvfs_link() fails with ENOENT if i_nlink is zero, this is done to prevent\nresurrecting already deleted files.\n\nFuse clears i_nlink on unlink even if there are other links pointing to the\nfile.\n\nReported-by: Anand Avati \u003cavati@redhat.com\u003e\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\n" }, { "commit": "6733e54b669c600eb8e451939ad55130db664fed", "tree": "2a8c24c856fa3f5d7d58a3eb39da943ca1c57e65", "parents": [ "bcf8a3dfcb274cf6654a19e12e244f3af8c0d355", "451d0f599934fd97faf54a5d7954b518e66192cb" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 12 12:39:21 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 12 12:39:21 2012 -0800" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse:\n FUSE: Notifying the kernel of deletion.\n fuse: support ioctl on directories\n fuse: Use kcalloc instead of kzalloc to allocate array\n fuse: llseek optimize SEEK_CUR and SEEK_SET\n" }, { "commit": "34c80b1d93e6e20ca9dea0baf583a5b5510d92d4", "tree": "7dcbf0a4e09464247e6992c8f44fcc872867bd3a", "parents": [ "a6322de67b58a00e3a783ad9c87c2a11b2d67b47" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu Dec 08 21:32:45 2011 -0500" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Fri Jan 06 23:19:54 2012 -0500" }, "message": "vfs: switch -\u003eshow_options() to struct dentry *\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "541af6a07474352e2143a0527c2b62b732439815", "tree": "fd52fd528264926d42804676278b43baac97e300", "parents": [ "632861f05a8e5878a267d173000880ceb608b56e" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Jul 26 03:17:33 2011 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Jan 03 22:55:07 2012 -0500" }, "message": "fuse: propagate umode_t\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "1a67aafb5f72a436ca044293309fa7e6351d6a35", "tree": "d9e58600148de9d41b478cf815773b746647d15b", "parents": [ "4acdaf27ebe2034c342f3be57ef49aed1ad885ef" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Jul 26 01:52:52 2011 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Jan 03 22:54:54 2012 -0500" }, "message": "switch -\u003emknod() to umode_t\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "4acdaf27ebe2034c342f3be57ef49aed1ad885ef", "tree": "d89a876ee19cd88609a587f8aa6c464a52ee6d98", "parents": [ "18bb1db3e7607e4a997d50991a6f9fa5b0f8722c" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Jul 26 01:42:34 2011 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Jan 03 22:54:53 2012 -0500" }, "message": "switch -\u003ecreate() to umode_t\n\nvfs_create() ignores everything outside of 16bit subset of its\nmode argument;

userspace\n unconditionally (if userspace sets FUSE_POSIX_LOCKS)\n\n - it doesn\u0027t cater for the fact that flock locks are automatically\n unlocked on file release\n\n - it doesn\u0027t take into account the fact that flock exclusive locks\n (write locks) don\u0027t need an fd opened for write.\n\nThe last one invalidates the original premise of the patch that flock\nlocks can be emulated with POSIX locks.\n\nThis patch fixes the first two issues. The last one needs to be fixed\nin userspace if the filesystem assumed that a write lock will happen\nonly on a file operned for write (as in the case of the current fuse\nlibrary).\n\nReported-by: Sebastian Pipping \u003cwebmaster@hartwork.org\u003e\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\n" }, { "commit": "2dad3206db5c3832cde1f58650027fea3ff7adf3", "tree": "96314a554afdab5904a939793156d4ae23ec11c1", "parents": [ "84635d68be4b846ba984a89f386524153330c597", "0c12eaffdf09466f36a9ffe970dda8f4aeb6efc0" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 22:49:19 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 22:49:19 2011 -0700" }, "message": "Merge branch \u0027for-3.1\u0027 of git://linux-nfs.org/~bfields/linux\n\n* \u0027for-3.1\u0027 of git://linux-nfs.org/~bfields/linux:\n nfsd: don\u0027t break lease on CLAIM_DELEGATE_CUR\n locks: rename lock-manager ops\n nfsd4: update nfsv4.1 implementation notes\n nfsd: turn on reply cache for NFSv4\n nfsd4: call nfsd4_release_compoundargs from pc_release\n nfsd41: Deny new lock before RECLAIM_COMPLETE done\n fs: locks: remove init_once\n nfsd41: check the size of request\n nfsd41: error out when client sets maxreq_sz or maxresp_sz too small\n nfsd4: fix file leak on open_downgrade\n nfsd4: remember to put RW access on stateid destruction\n NFSD: Added TEST_STATEID operation\n NFSD: added FREE_STATEID operation\n svcrpc: fix list-corrupting race on nfsd shutdown\n rpc: allow autoloading of gss mechanisms\n svcauth_unix.c: quiet sparse noise\n svcsock.c: include sunrpc.h to quiet sparse noise\n nfsd: Remove deprecated nfsctl system call and related code.\n NFSD: allow OP_DESTROY_CLIENTID to be only op in COMPOUND\n\nFix up trivial conflicts in Documentation/feature-removal-schedule.txt\n" }, { "commit": "02c24a82187d5a628c68edfe71ae60dc135cd178", "tree": "c8dbaba4d82e2b20ed4335910a564a1f7d90fcf6", "parents": [ "22735068d53c7115e384bc88dea95b17e76a6839" ], "author": { "name": "Josef Bacik", "email": "josef@redhat.com", "time": "Sat Jul 16 20:44:56 2011 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Jul 20 20:47:59 2011 -0400" }, "message": "fs: push i_mutex and filemap_write_and_wait down into -\u003efsync() handlers\n\nBtrfs needs to be able to control how filemap_write_and_wait_range() is called\nin fsync to make it less of a painful operation, so push down taking i_mutex and\nthe calling of filemap_write_and_wait() down into the -\u003efsync() handlers.
