| H A D | extents.c | diff 61628a3f3a37af2bf25daf8e26fd6b76a78c4f76 Fri Jul 11 18:27:31 CDT 2008 Mingming Cao <cmm@us.ibm.com> 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.
