This patch adds tests for the return value of sb_getblk() in the ext2/3 filesystems. In fs/buffer.c it is stated that the getblk() function never fails. However, it does can return NULL in some situations due to I/O errors, which may lead us to NULL pointer dereferences Signed-off-by: NGlauber de Oliveira Costa <glommer@br.ibm.com> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

I noticed some problems while running ext3 with the debug flag set on. More precisely, I was unable to umount the filesystem. Some investigation took me to the patch that follows. At a first glance , the lock/unlock I've taken out seems really not necessary, as the main code (outside debug) does not lock the super. The only additional danger operations that debug code introduces seems to be related to bitmap, but bitmap operations tends to be all atomic anyway. I also took the opportunity to fix 2 spelling errors. Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

- ->releasepage() annotated (s/int/gfp_t), instances updated - missing gfp_t in fs/* added - fixed misannotation from the original sweep caught by bitwise checks: XFS used __nocast both for gfp_t and for flags used by XFS allocator. The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.

Update the file systems in fs/ implementing a delete_inode() callback to call truncate_inode_pages(). One implementation note: In developing this patch I put the calls to truncate_inode_pages() at the very top of those filesystems delete_inode() callbacks in order to retain the previous behavior. I'm guessing that some of those could probably be optimized.

We are not using the in-inode space for xattrs in reserved inodes because mkfs.ext3 doesn't initialize it properly. For those inodes, we set i_extra_isize to 0. Make sure that we also don't overwrite the i_extra_isize field when writing out the inode in that case. This is for cleanliness only, and doesn't fix an actual bug.

Use improved credits estimates for quota operations. Also reserve a space for a quota operation in a transaction only if filesystem was mounted with some quota options.

This had a fatal lock ranking bug: we do journal_start outside mpage_writepages()'s lock_page(). Revert the whole thing, think again. Credit-to: Jan Kara <jack@suse.cz> For identifying the bug.

The extra race-with-truncate-then-retry logic around ext3_get_block_handle(), which was inherited from ext2, becomes unecessary for ext3, since we have already obtained the ei->truncate_sem in ext3_get_block_handle() before calling ext3_alloc_branch(). The ei->truncate_sem is already there to block concurrent truncate and block allocation on the same inode. So the inode's indirect addressing tree won't be changed after we grab that semaphore. We could, after get the semaphore, re-verify the branch is up-to-date or not. If it has been changed, then get the updated branch. If we still need block allocation, we will have a safe version of the branch to work with in the ext3_find_goal()/ext3_splice_branch(). The code becomes more readable after remove those retry logic. The patch also clean up some gotos in ext3_get_block_handle() to make it more readable.

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!
