Messages in this thread Patch in this message |  | | | Subject | [PATCH] wait_task_stopped: pass correct exit_code to wait_noreap_copyout | | From | Scott James Remnant <> | | Date | Sun, 18 Nov 2007 09:13:24 +0000 | |
In wait_task_stopped() exit_code already contains the right value for
the si_status member of siginfo, and this is simply set in the non
WNOWAIT case.
Pass it unchanged to wait_noreap_copyout(); we would only need to
shift it and add 0x7f if we were returning it in the user status field
and that isn't used for any function that permits WNOWAIT.
