JFS: Improve sync barrier processing
Under heavy load, hot metadata pages are often locked by non-committed transactions, making them difficult to flush to disk. This prevents the sync point from advancing past a transaction that had modified the page. There is a point during the sync barrier processing where all outstanding transactions have been committed to disk, but no new transaction have been allowed to proceed. This is the best time to write the metadata. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
