ext4: Rename ext4dev to ext4

2008-10-11T00:02:48Z

The ext4 filesystem is getting stable enough that it's time to drop the "dev" prefix. Also remove the requirement for the TEST_FILESYS flag. Signed-off-by: "Theodore Ts'o"

Hook ext4 to the vfs fiemap interface.

2008-10-07T04:46:36Z

ext4_ext_walk_space() was reinstated to be used for iterating over file extents with a callback; it is used by the ext4 fiemap implementation. Signed-off-by: Eric Sandeen Signed-off-by: "Theodore Ts'o" Cc: linux-ext4@vger.kernel.org Cc: linux-fsdevel@vger.kernel.org

ext4: delayed allocation i_blocks fix for stat

2008-07-11T23:27:31Z

Right now i_blocks is not getting updated until the blocks are actually allocaed on disk. This means with delayed allocation, right after files are copied, "ls -sF" shoes the file as taking 0 blocks on disk. "du" also shows the files taking zero space, which is highly confusing to the user. Since delayed allocation already keeps track of per-inode total number of blocks that are subject to delayed allocation, this patch fix this by using that to adjust the value returned by stat(2). When real block allocation is done, the i_blocks will get updated. Since the reserved blocks for delayed allocation will be decreased, this will be keep value returned by stat(2) consistent.

ext4: Use page_mkwrite vma_operations to get mmap write notification.

2008-07-11T23:27:31Z

We would like to get notified when we are doing a write on mmap section. This is needed with respect to preallocated area. We split the preallocated area into initialzed extent and uninitialzed extent in the call back. This let us handle ENOSPC better. Otherwise we get ENOSPC in the writepage and that would result in data loss. The changes are also needed to handle ENOSPC when writing to an mmap section of files with holes.

ext4: move headers out of include/linux

2008-04-29T22:13:32Z

Move ext4 headers out of include/linux. This is just the trivial move, there's some more thing that could be done later. Signed-off-by: Christoph Hellwig Signed-off-by: Mingming Cao Signed-off-by: "Theodore Ts'o"

Convert ext4 to use unlocked_ioctl

2008-04-30T02:03:54Z

I checked ext4_ioctl and it looked largely safe to not be used without BKL. So convert it over to unlocked_ioctl. Signed-off-by: Andi Kleen Signed-off-by: Theodore Ts'o

ext4: Convert truncate_mutex to read write semaphore.

2008-01-29T04:58:26Z

We are currently taking the truncate_mutex for every read. This would have performance impact on large CPU configuration. Convert the lock to read write semaphore and take read lock when we are trying to read the file. Signed-off-by: Aneesh Kumar K.V

ext4: store maxbytes for bitmapped files and return EFBIG as appropriate

2008-01-29T04:58:27Z

Calculate & store the max offset for bitmapped files, and catch too-large seeks, truncates, and writes in ext4, shortening or rejecting as appropriate. Signed-off-by: Eric Sandeen
