+From 34b91edc70709f32b44f6b3a32c8f18db393e36c Mon Sep 17 00:00:00 2001
+From: =?UTF-8?q?Daniel=20D=C3=ADaz?= <daniel.diaz@linaro.org>

+Subject: [PATCH] Define __SIGRTMIN and __SIGRTMAX for MUSL
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Some libc implementations might differ in the definitions they
+include. Exempli gratia: MUSL does not define __SIGRTMAX nor
+__SIGRTMIN.
+
+These two tests fail to build because of the missing
+definitions:
+  testcases/kernel/syscalls/ptrace/ptrace05.c
+  testcases/kernel/syscalls/sighold/sighold02.c
+
+Out of precaution, these two also include this header:
+  lib/tst_sig.c
+  testcases/kernel/syscalls/rt_sigsuspend/rt_sigsuspend01.c
+
+Upstream-Status: Submitted [http://lists.linux.it/pipermail/ltp/2019-February/010916.html]
