The patch titled
wait_task_stopped(): pass correct exit_code to wait_noreap_copyout()
has been removed from the -mm tree. Its filename was
wait_task_stopped-pass-correct-exit_code-to.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: wait_task_stopped(): pass correct exit_code to wait_noreap_copyout()
From: Scott James Remnant <scott@xxxxxxxxxx>
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.
If you call waitid() with a stopped or traced process, you'll get the signal
in siginfo.si_status as expected -- however if you call waitid(WNOWAIT) at the
same time, you'll get the signal << 8 | 0x7f
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.
