The newly introduced cgroup_show_path has an extraneous variable that gcc warns about: kernel/cgroup.c: In function 'cgroup_show_path': kernel/cgroup.c:1634:15: error: unused variable 'ret' [-Werror=unused-variable] int len = 0, ret = 0; This must have been left over from a previous version that was changed before it got committed. I checked the function and found that two other variables in the same function have an extraneous initialization, presumably another artifact from the same rework. This patch removes the useless warning and the extra initializations. Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- kernel/cgroup.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) -- 2.7.0
