[PATCH] JFS: Write journal sync points more often
This patch adds jfs_syncpt, which calls lmLogSync to write sync points to the journal both in jfs_sync_fs and when sync barrier processing completes. lmLogSync accomplishes two things: 1) it pushes logged-but-dirty metadata pages to disk, and 2) it writes a sync record to the journal so that jfs_fsck doesn't need to replay more transactions than is necessary.
