2013-03-20ext3: fix data=journal fast mount/umount hangJan Kara
In data=journal mode, if we unmount the file system before a transaction has a chance to complete, when the journal inode is being evicted, we can end up calling into log_wait_commit() for the last transaction, after the journalling machinery has been shut down. That triggers the WARN_ONCE in __log_start_commit(). Arguably we should adjust ext3_should_journal_data() to return FALSE for the journal inode, but the only place it matters is ext3_evict_inode(), and so it's to save a bit of CPU time, and to make the patch much more obviously correct by inspection(tm), we'll fix it by explicitly not trying to waiting for a journal commit when we are evicting the journal inode, since it's guaranteed to never succeed in this case. This can be easily replicated via: mount -t ext3 -o data=journal /dev/vdb /vdb ; umount /vdb This is a port of ext4 fix from Ted Ts'o. Signed-off-by: Jan Kara <jack@suse.cz>

2012-09-04ext3: Fix fdatasync() for files with only i_size changesJan Kara
Code tracking when transaction needs to be committed on fdatasync(2) forgets to handle a situation when only inode's i_size is changed. Thus in such situations fdatasync(2) doesn't force transaction with new i_size to disk and that can result in wrong i_size after a crash. Fix the issue by updating inode's i_datasync_tid whenever its size is updated.

2012-01-09ext3: Don't warn from writepage when readonly inode is spotted after errorJan Kara
WARN_ON_ONCE(IS_RDONLY(inode)) tends to trip when filesystem hits error and is remounted read-only. This unnecessarily scares users (well, they should be scared because of filesystem error, but the stack trace distracts them from the right source of their fear ;-). We could as well just remove the WARN_ON but it's not hard to fix it to not trip on filesystem with errors and not use more cycles in the common case so that's what we do.

2011-07-23ext3: Fix data corruption in inodes with journalled dataJan Kara
When journalling data for an inode (either because it is a symlink or because the filesystem is mounted in data=journal mode), ext3_evict_inode() can discard unwritten data by calling truncate_inode_pages(). This is because we don't mark the buffer / page dirty when journalling data but only add the buffer to the running transaction and thus mm does not know there are still unwritten data. Fix the problem by carefully tracking transaction containing inode's data, committing this transaction, and writing uncheckpointed buffers when inode should be reaped.

2011-07-20fs: simplify the blockdev_direct_IO prototypeChristoph Hellwig
Simple filesystems always pass inode->i_sb_bdev as the block device argument, and never need a end_io handler. Let's simply things for them and for my grepping activity by dropping these arguments. The only thing not falling into that scheme is ext4, which passes and end_io handler without needing special flags (yet), but given how messy the direct I/O code there is use of __blockdev_direct_IO in one instead of two out of three cases isn't going to make a large difference anyway.

2011-06-25ext3: Improve truncate error handlingJan Kara
New truncate calling convention allows us to handle errors from ext3_block_truncate_page(). So reorganize the code so that ext3_block_truncate_page() is called before we change inode size. This also removes unnecessary block zeroing from error recovery after failed buffered writes (zeroing isn't needed because we could have never written non-zero data to disk). We have to be careful and keep zeroing in direct IO write error recovery because there we might have already overwritten end of the last file block. Signed-off-by: Jan Kara <jack@suse.cz>
2011-06-25ext3: Convert ext3 to new truncate calling conventionJan Kara
Mostly trivial conversion. We fix a bug that IS_IMMUTABLE and IS_APPEND files could not be truncated during failed writes as we change the code.

Tell the filesystem if we just updated timestamp (I_DIRTY_SYNC) or anything else, so that the filesystem can track internally if it needs to push out a transaction for fdatasync or not. This is just the prototype change with no user for it yet. I plan to push large XFS changes for the next merge window, and getting this trivial infrastructure in this window would help a lot to avoid tree interdependencies. Also remove incorrect comments that ->dirty_inode can't block. That has been changed a long time ago, and many implementations rely on it.

2010-08-09remove inode_setattrChristoph Hellwig
Replace inode_setattr with opencoded variants of it in all callers. This moves the remaining call to vmtruncate into the filesystem methods where it can be replaced with the proper truncate sequence. In a few cases it was obvious that we would never end up calling vmtruncate so it was left out in the opencoded variant: spufs: explicitly checks for ATTR_SIZE earlier btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above In addition to that ncpfs called inode_setattr with handcrafted iattrs, which allowed to trim down the opencoded variant.

2010-08-09introduce __block_write_beginChristoph Hellwig
Split up the block_write_begin implementation - __block_write_begin is a new trivial wrapper for block_prepare_write that always takes an already allocated page and can be either called from block_write_begin or filesystem code that already has a page allocated. Remove the handling of already allocated pages from block_write_begin after switching all callers that do it to __block_write_begin.

2010-08-09sort out blockdev_direct_IO variantsChristoph Hellwig
Move the call to vmtruncate to get rid of accessive blocks to the callers in prepearation of the new truncate calling sequence. This was only done for DIO_LOCKING filesystems, so the __blockdev_direct_IO_newtrunc variant was not needed anyway. Get rid of blockdev_direct_IO_no_locking and its _newtrunc variant while at it as just opencoding the two additional paramters is shorted than the name suffix.

2010-08-05ext3: Fix dirtying of journalled buffers in data=journal modeJan Kara
In data=journal mode, we still use block_write_begin() to prepare page for writing. This function can occasionally mark buffer dirty which violates journalling assumptions - when a buffer is part of a transaction, it should be dirty and a buffer can be already part of a forget list of some transaction when block_write_begin() gets called. This violation of journalling assumptions then results in "JBD: Spotted dirty metadata buffer..." warnings. In fact, temporary dirtying the buffer while the page is still locked does not really cause problems to the journalling because we won't write the buffer until the page gets unlocked. So we just have to make sure to clear dirty bits before unlocking the page. Reviewed-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Jan Kara <jack@suse.cz>
2010-07-21ext3: Avoid filesystem corruption after a crash under heavy delete loadJan Kara
It can happen that ext3_free_branches calls ext3_forget() for an indirect block in an earlier transaction than a transaction in which we clear pointer to this indirect block. Thus if we crash before a transaction clearing the block pointer is committed, we will see indirect block pointing to already freed blocks and complain during orphan list cleanup. The fix is simple: Make sure ext3_forget() is called in the transaction doing block pointer clearing. This is a backport of an ext4 fix by Amir G. <amir73il@users.sourceforge.net> Signed-off-by: Jan Kara <jack@suse.cz>
2010-07-21ext3: remove vestiges of nobh supportChristoph Hellwig

2010-05-21quota: unify quota init condition in setattrDmitry Monakhov
Quota must being initialized if size or uid/git changes requested. But initialization performed in two different places: in case of i_size file system is responsible for dquot init , but in case of uid/gid init will be called internally in dquot_transfer(). This ambiguity makes code harder to understand. Let's move this logic to one common helper function. Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Jan Kara <jack@suse.cz>
