Subject: [PATCH] tune2fs: do not change j_tail_sequence in journal superblock

The function recover_ext3_journal in debugfs/journal.c, if the log 
replay is over,
the j_tail_sequence in journal superblock is not changed to the value of 
the last
transaction sequence, this will cause subsequent log commitids to count 
from the
commitid in last time.
After tune2fs -e, the log commitid is counted from the commitid in last 
time, if
the log ID of the current operation overlaps with that of the last 
operation, this
will cause logs that were previously replayed by tune2fs to be replayed
