Wang Shilong 3cb0929ad2 Btrfs: fix wrong super generation mismatch when scrubbing supers ... We came a race condition when scrubbing superblocks, the story is: In commiting transaction, we will update @last_trans_commited after writting superblocks, if scrubber start after writting superblocks and before updating @last_trans_commited, generation mismatch happens! We fix this by checking @scrub_pause_req, and we won't start a srubber until commiting transaction is finished.(after btrfs_scrub_continue() finished.)
