Module Name: src
Committed By: pgoyette
Date: Tue Oct 13 00:24:35 UTC 2015
Modified Files:
src/sys/kern: kern_exec.c
Log Message:
In execve_runproc(), update the p_waited entry for the process being
moved to SSTOP state, not for its parent. (It is correct to update
the parent's p_nstopchild count.) If the value is not already zero,
it could prevent its parent from waiting for the process.
Fixes PR kern/50298
