Subject: [PATCH 09/14] staging: lustre: lnet-route: use kmalloc for small allocation
Date: Tue, 09 Jan 2018 12:19:38 +1100	[thread overview]
Message-ID: <151546077849.9776.5734351152485517837.stgit@noble> (raw)
In-Reply-To: <151546052331.9776.7408338350463291753.stgit@noble>

This allocation is reasonably small.
As the function is called "*_locked", it might not be safe
to perform a GFP_KERNEL allocation, so be safe and
use GFP_NOFS.
