Build Update for openvswitch/ovs
-------------------------------------
Build: #7900
Status: Passed
Duration: 1 hr, 20 mins, and 8 secs
Commit: b82a90e (master)
Author: Flavio Leitner
Message: rhel: limit stack size to 2M.
The default stack size in Fedora/RHEL is 8M, which means when ovs-vswitchd
daemon starts and uses --mlockall (default), it will dirty all memory
regions for all threads which is proportionally to the number of CPUs.
On a big host this increases memory usage to many hundreds of megabytes
while OVS actually requires much less.
This patch relies on systemd to limit to 2M/thread. That is much more
than the minimum documented at function ovs_thread_create():
/* Some small systems use a default stack size as small as 80 kB, but OVS
* requires approximately 384 kB according to the following analysis:
* https://mail.openvswitch.org/pipermail/ovs-dev/2016-January/308592.html
*
* We use 512 kB to give us some margin of error. */
