Pull xfs fixes from Darrick Wong: "A handful more bug fixes for you today. Changes since last time: - Don't leak resources when mount fails - Don't accidentally clobber variables when looking for free inodes" * tag 'xfs-4.13-fixes-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: don't leak quotacheck dquots when cow recovery xfs: clear MS_ACTIVE after finishing log recovery iomap: fix integer truncation issues in the zeroing and dirtying helpers xfs: fix inobt inode allocation search optimization
