stress-vforkmany: remove as many calls as possible
We should remove as many function calls so we don't clobber the stack.
Signed-off-by: Colin Ian King <colin.k...@canonical.com>
..the code added a wrapper process to ensure that kill'd vfork children
were respawned, however, the non-OOM-able setting on the vfork processes
were causing the OOM killer to reap everything except the vfork
children.
I've fixed this with upstream fix:
http://kernel.ubuntu.com/git/cking/stress-
ng.git/commit/?id=5f3c93335def9985d479e891f3eb5939c1dd3797
This now makes vfork processes OOM-able by default.
