+Subject: [LTP] [PATCH] syscalls: rt_sigwaitinfo01: Fix failure for MIPS arches
+
+rt_sigtimedwait01 fails as follow on MIPS arches
+rt_sigtimedwait01    1  TFAIL  :  .../sigwaitinfo01.c:58: test_empty_set
+(.../sigwaitinfo01.c: 148): Unexpected failure:
+TEST_ERRNO=EINVAL(22): Invalid argument
+
+As this case purposely bypasses glibc, it should align with the size of kernel
+definition of sigset_t which is different from other arches.
+https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/mips/include/uapi/asm/signal.h#n15
+
+This patch adds specific case for MIPS.
