+Subject: [PATCH] bits/siginfo-consts.h: enum definition for TRAP_HWBKPT is missing
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Compile following linux kernel test code with latest glibc:
+
+https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/testing/selftests/breakpoints/breakpoint_test_arm64.c
+
+and we get following error:
+breakpoint_test_arm64.c: In function ‘run_test’:
+breakpoint_test_arm64.c:171:25: error: ‘TRAP_HWBKPT’ undeclared (first use in this function)
+  if (siginfo.si_code != TRAP_HWBKPT) {
+                         ^
+I can compile test code by modifying my local
+/usr/include/bits/siginfo.h and test works great. Therefore, this patch
+will be needed in upstream glibc so that issue is fixed there as well.
