From: Alexandru Ardelean <ardeleanalex@gmail.com>

Date: Thu, 4 Feb 2016 09:20:34 +0200
|
||||
Subject: [PATCH] lib/ovs-thread: Ensure that thread stacks are always at least
|
||||
512 kB.
|
||||
|
||||
This makes a difference for libc implementations (such as musl libc) that
|
||||
have a really small default pthread stack size.
|
||||
|
||||
Will reference this discussion:
