ext4: add checks for errors from jbd2

2008-10-11T00:29:21Z

If the journal has aborted due to a checkpointing failure, we have to keep the contents of the journal space. Otherwise, the filesystem will lose uncheckpointed metadata completely and become inconsistent. To avoid this, we need to keep needs_recovery flag if checkpoint has failed. With this patch, ext4_put_super() detects a checkpointing failure from the return value of journal_destroy(), then it invokes ext4_abort() to make the filesystem read only and keep needs_recovery flag. Errors from jbd2_journal_flush() are also handled by this patch in some places. Signed-off-by: Hidehiro Kawai Signed-off-by: Theodore Ts'o

ext4: hook the ext3 migration interface to the EXT4_IOC_SETFLAGS ioctl

2008-10-09T03:34:06Z

This patch hooks the ext3 to ext4 migrate interface to EXT4_IOC_SETFLAGS ioctl. The userspace interface is via chattr +e. We only allow setting extent flags. Clearing extent flag (migrating from ext4 to ext3) is not supported. Signed-off-by: Aneesh Kumar K.V Signed-off-by: "Theodore Ts'o"

ext4: elevate write count for migrate ioctl

2008-09-13T16:52:26Z

The migrate ioctl writes to the filsystem, so we need to elevate the write count. Signed-off-by: Aneesh Kumar K.V Signed-off-by: "Theodore Ts'o"

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

[PATCH] r/o bind mounts: elevate write count for ioctls()

2008-04-19T04:29:24Z

Some ioctl()s can cause writes to the filesystem. Take these, and make them use mnt_want/drop_write() instead. [AV: updated] Acked-by: Al Viro Signed-off-by: Christoph Hellwig Signed-off-by: Dave Hansen Signed-off-by: Andrew Morton Signed-off-by: Al Viro

ext4: Add EXT4_IOC_MIGRATE ioctl

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
