Subject: [PATCH AUTOSEL 4.19 032/219] RDMA/vmw_pvrdma: Use atomic memory allocation in create AH
Date: Fri, 22 Nov 2019 00:46:04 -0500	[thread overview]
Message-ID: <20191122054911.1750-25-sashal@kernel.org> (raw)
In-Reply-To: <20191122054911.1750-1-sashal@kernel.org>

From: Gal Pressman <galpress@amazon.com>

[ Upstream commit a276a4d93bf1580d737f38d1810e5f4b166f3edd ]

Create address handle callback should not sleep, use GFP_ATOMIC instead of
GFP_KERNEL for memory allocation.

Fixes: 29c8d9eba550 ("IB: Add vmw_pvrdma driver")
