[GIT PULL v3] Btrfs: improve write ahead log with sub transaction
I''ve been working to try to improve the write-ahead log''s performance,
and I found that the bottleneck addresses in the checksum items,
especially when we want to make a random write on a large file, e.g a 4G file.
Then a idea for this suggested by Chris is to use sub transaction ids and just
