Module Name:    src
Committed By:   kamil
Date:           Mon May  4 20:55:48 UTC 2020

Modified Files:
        src/tests/lib/libc/sys: t_ptrace_wait.c
Added Files:
        src/tests/lib/libc/sys: t_ptrace_register_wait.h

Log Message:
Move register tests out of t_ptrace_wait.c to t_ptrace_register_wait.h

The same tests are now included with the preprocessor in t_ptrace_wait.c.

No functional change intended.
