Modified Files: src/tests/lib/libc/sys: t_ptrace_wait.c Added Files: src/tests/lib/libc/sys: t_ptrace_eventmask_wait.h Log Message: Move eventmask tests out of t_ptrace_wait.c to t_ptrace_eventmask_wait.h The same tests are now included with the preprocessor in t_ptrace_wait.c. No functional change intended.
