From 0d399205edf3a4c290e76ebb36e541593af4a1b4 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Sat, 16 Apr 2011 06:55:39 -0400 Subject: Btrfs end_bio_extent_readpage should look for locked bits A recent commit caches the extent state in end_bio_extent_readpage, but the search it does should look for locked extents. This fixes things to make it more effective.
