Colin Ian King 41a0c249cb proc: fix -ESRCH error when writing to /proc/$pid/coredump_filter ... Writing to /proc/$pid/coredump_filter always returns -ESRCH because commit 774636e19e ("proc: convert to kstrto*()/kstrto*_from_user()") removed the setting of ret after the get_proc_task call and incorrectly left it as -ESRCH. Instead, return 0 when successful. Example breakage: echo 0 > /proc/self/coredump_filter bash: echo: write error: No such process Fixes: 774636e19e ("proc: convert to kstrto*()/kstrto*_from_user()") Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: Kees Cook <keescook@chromium.org> Cc: <stable@vger.kernel.org> [4.3+] Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2015-12-18 14:25:40 -08:00
