Jan Kara 6e06ae88ed jbd2: speedup jbd2_journal_dirty_metadata() ... It is often the case that we mark buffer as having dirty metadata when the buffer is already in that state (frequent for bitmaps, inode table blocks, superblock). Thus it is unnecessary to contend on grabbing journal head reference and bh_state lock. Avoid that by checking whether any modification to the buffer is needed before grabbing any locks or references. [ Note: this is a fixed version of commit 2143c1965a, which was reverted in ebeaa8ddb3 due to a false positive triggering of an assertion check. -- Ted ] Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Theodore Ts'o <tytso@mit.edu>		2015-07-12 18:11:30 -04:00
