From: Filipe David Borba Manana Date: Fri, 16 Aug 2013 14:23:33 +0000 (+0100) Subject: Btrfs: reset force_compress on btrfs_file_defrag failure X-Git-Tag: v3.12-rc2~5^2~68 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=633085c79c84c391732caa40f5b3a3d2b299f7be;p=profile%2Fivi%2Fkernel-x86-ivi.git Btrfs: reset force_compress on btrfs_file_defrag failure After we set force_compress with a new value (which was not being done while holding the inode mutex), if an error happens and we jump to the label out_ra, the force_compress property of the inode is not set to BTRFS_COMPRESS_NONE (unlike in the case where no errors happen).
