+Subject: [PATCH] Fix invalid sigprocmask call
+
+The POSIX document says
+
+ The pthread_sigmask() and sigprocmask() functions shall fail if:
+
+ [EINVAL]
+ The value of the how argument is not equal to one of the defined values.
+
+and this is how musl-libc is currently doing. Fix the call to be safe
+and correct
