This fixes up a compile warning [-Wunused-but-set-variable] - given the comments in userspace_set_region_sync() the non-reporting of errors seems intentional so the return value can be dropped to make gcc happy. Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> --- CC [M] drivers/md/dm-log-userspace-base.o drivers/md/dm-log-userspace-base.c: In function 'userspace_set_region_sync': drivers/md/dm-log-userspace-base.c:744:6: warning: variable 'r' set but not used [-Wunused-but-set-variable] The comment here states: /* * It would be nice to be able to report failures. * However, it is easy emough to detect and resolve. */ note though that userspace_do_request() calls dm_consult_userspace() which can also return -EINVAL (which is though reported in dm_consult_userspace via DMINFO if I got it right) Patch was only compile tested with x86_64_defconfig + CONFIG_DM_LOG_USERSPACE Patch is against 4.0-rc3 (localversion-next is -next-20150313) drivers/md/dm-log-userspace-base.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-)
