Mingming Cao 61628a3f3a ext4: Invert lock ordering of page_lock and transaction start in delalloc ... With the reverse locking, we need to start a transation before taking the page lock, so in ext4_da_writepages() we need to break the write-out into chunks, and restart the journal for each chunck to ensure the write-out fits in a single transaction. Updated patch from Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> which fixes delalloc sync hang with journal lock inversion, and address the performance regression issue.
