From 20cb52ebd1b5ca6fa8a5d9b6b1392292f5ca8a45 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 24 Jun 2010 09:46:01 +1000 Subject: xfs: simplify xfs_vm_writepage The writepage implementation in XFS still tries to deal with dirty but unmapped buffers which used to caused by writes through shared mmaps. Since the introduction of ->page_mkwrite these can't happen anymore, so remove the code dealing with them. Note that the all_bh variable which causes us to start I/O on all buffers on the pages was controlled by the count of unmapped buffers, which also included those not actually dirty. It's now unconditionally initialized to 0 but set to 1 for the case of small file size extensions. It probably can be removed entirely, but that's left for another patch.
