* ext2: remove useless call to brelse() in ext2_free_inode()Francis Moreau2010-05-211-5/+4Star
| | | | | | | | This patch removes a useless call to brelse(bitmap_bh) since at that point bitmap_bh is NULL and slightly cleans up bitmap_bh handling. Signed-off-by: Francis Moreau <francis.moro@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>
* dquot: cleanup dquot initialize routineChristoph Hellwig2010-03-051-1/+1
| | | | | | | | | | | | Get rid of the initialize dquot operation - it is now always called from the filesystem and if a filesystem really needs it's own (which none currently does) it can just call into it's own routine directly. Rename the now static low-level dquot_initialize helper to __dquot_initialize and vfs_dq_init to dquot_initialize to have a consistent namespace.

* dquot: cleanup inode allocation / freeing routinesChristoph Hellwig2010-03-051-5/+5
| | | | | | | | | | | | | | Get rid of the alloc_inode and free_inode dquot operations - they are always called from the filesystem and if a filesystem really needs their own (which none currently does) it can just call into it's own routine directly. Also get rid of the vfs_dq_alloc/vfs_dq_free wrappers and always call the lowlevel dquot_alloc_inode / dqout_free_inode routines directly, which now lose the number argument which is always 1.

* ext2: tighten restrictions on inode flagsDuane Griffin2009-01-081-6/+2Star
| | | | | | | | | | | | | | | | | | At the moment there are few restrictions on which flags may be set on which inodes. Specifically DIRSYNC may only be set on directories and IMMUTABLE and APPEND may not be set on links. Tighten that to disallow TOPDIR being set on non-directories and only NODUMP and NOATIME to be set on non-regular file, non-directories. Introduces a flags masking function which masks flags based on mode and use it during inode creation and when flags are set via the ioctl to facilitate future consistency.

* ext2: don't inherit inappropriate inode flags from parentDuane Griffin2009-01-081-1/+1
| | | | | | | | | | | | | | | | At present BTREE/INDEX is the only flag that new ext2 inodes do NOT inherit from their parent. In addition prevent the flags DIRTY, ECOMPR, INDEX, IMAGIC and TOPDIR from being inherited. List inheritable flags explicitly to prevent future flags from accidentally being inherited. This fixes the TOPDIR flag inheritance bug reported at http://bugzilla.kernel.org/show_bug.cgi?id=9866.

* nfsd race fixes: ext2Al Viro2009-01-011-1/+5
| | | | | | | | | | | | | | | | | | | | | | | * make ext2_new_inode() put the inode into icache in locked state * do not unlock until the inode is fully set up; otherwise nfsd might pick it in half-baked state. * make sure that ext2_new_inode() does *not* lead to two inodes with the same inumber hashed at the same time; otherwise a bogus fhandle coming from nfsd might race with inode creation: nfsd: iget_locked() creates inode nfsd: try to read from disk, block on that. ext2_new_inode(): allocate inode with that inumber ext2_new_inode(): insert it into icache, set it up and dirty ext2_write_inode(): get the relevant part of inode table in cache, set the entry for our inode (and start writing to disk) nfsd: get CPU again, look into inode table, see nice and sane on-disk inode, set the in-core inode from it oops - we have two in-core inodes with the same inumber live in icache, both used for IO.

* CRED: Wrap task credential accesses in the Ext2 filesystemDavid Howells2008-11-141-2/+2
| | | | | | | | | | | | | | | | | Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

| | | | | | | | | | | | ext[234]_get_group_desc never tests the bh argument, and only sets it if it is passed in; it is perfectly happy with a NULL bh argument. But, many callers send one in and never use it. May as well call with NULL like other callers who don't use the bh.

* [PATCH] inode-diet: Eliminate i_blksize from the inode structureTheodore Ts'o2006-09-271-1/+0Star
| | | | | | | | | | | | | | | | This eliminates the i_blksize field from struct inode. Filesystems that want to provide a per-inode st_blksize can do so by providing their own getattr routine instead of using the generic_fillattr() function. Note that some filesystems were providing pretty much random (and incorrect) values for i_blksize.

(30% degradation running dbench with 16 threads) Commit 21730eed11de42f22afcbd43f450a1872a0b5ea1, which claims to make EXT2_DEBUG work again, moves the taking of the kernel lock out of debug-only code in ext2_count_free_inodes and ext2_count_free_blocks and into ext2_statfs.

* Linux-2.6.12-rc2Linus Torvalds2005-04-171-0/+735
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
