Zhang Yi 475e1be393 jbd2: speed up jbd2_transaction_committed() 
commit 7c73ddb7589fb8ddb1136b6306dfb72089c81511 upstream.

jbd2_transaction_committed() is used to check whether a transaction with
the given tid has already committed, it holds j_state_lock in read mode
and check the tid of current running transaction and committing
transaction, but holding the j_state_lock is expensive.

We have already stored the sequence number of the most recently
committed transaction in journal t->j_commit_sequence, we could do this
check by comparing it with the given tid instead. If the given tid isn't
smaller than j_commit_sequence, we can ensure that the given transaction
has been committed. That way we could drop the expensive lock and
achieve about 10% ~ 20% performance gains in concurrent DIOs on may
virtual machine with 100G ramdisk.

    -bs=4k -size=10G -numjobs=10 -runtime=60 -overwrite=1 -name=test \

Before:
  overwrite       IOPS=88.2k, BW=344MiB/s
  read            IOPS=95.7k, BW=374MiB/s
  rand overwrite  IOPS=98.7k, BW=386MiB/s
  randread        IOPS=102k, BW=397MiB/s

After:
  overwrite       IOPS=105k, BW=410MiB/s
  read            IOPS=112k, BW=436MiB/s
  rand overwrite  IOPS=104k, BW=404MiB/s
  randread        IOPS=111k, BW=432MiB/s
