Hello,

Yes, a libc wrapper would return -1, I've changed the wording and applied other suggestions.

funsafemath (2):
  man/man2/seccomp.2: Document SECCOMP_FILTER_FLAG_TSYNC_ESRCH
  man/man2/seccomp.2: Document SECCOMP_FILTER_FLAG_WAIT_KILLABLE_RECV

Thanks!  I've applied both patches.


Have a lovely night!
Alex
