+Subject: [PATCH] sigwaitinfo: Do not run invalid/undefined test cases
+
+These testcases run for eternity on musl
+
+test_bad_address* cases are passing invalid pointers to a function; that's always UB
+empty_set and timeout rely on the implementation-defined "may fail" for EINTR in sigtimedwait [1]
+
+normally "may fail" is an "unspecified" but here the impl
+is supposed to document it so it's "impl-defined"
+

+Upstream-Status: Submitted [https://patchwork.ozlabs.org/project/ltp/patch/20200528204556.2444156-1-raj.khem@gmail.com/]
