ext4: prepare to drop EXT4_STATE_DELALLOC_RESERVED
The EXT4_STATE_DELALLOC_RESERVED flag was originally implemented because it was too hard to make sure the mballoc and get_block flags could be reliably passed down through all of the codepaths that end up calling ext4_mb_new_blocks(). Since then, we have mb_flags passed down through most of the code paths, so getting rid of EXT4_STATE_DELALLOC_RESERVED isn't as tricky as it used to. This commit plumbs in the last of what is required, and then adds a WARN_ON check to make sure we haven't missed anything. If this passes a full regression test run, we can then drop EXT4_STATE_DELALLOC_RESERVED. Signed-off-by: Theodore Ts'o <tytso@mit.edu> Reviewed-by: Jan Kara <jack@suse.cz>
