Module Name: src
Committed By: kamil
Date: Mon May 4 21:21:30 UTC 2020
Modified Files:
src/tests/lib/libc/sys: t_ptrace_wait.c
Added Files:
src/tests/lib/libc/sys: t_ptrace_syscall_wait.h
Log Message:
Move syscall tests out of t_ptrace_wait.c to t_ptrace_syscall_wait.h
The same tests are now included with the preprocessor in t_ptrace_wait.c.
No functional change intended.
