Subject[PATCH 4.9 03/51] xen-netback: Use GFP_ATOMIC to allocate hash
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Anoob Soman <anoob.soman@citrix.com>


[ Upstream commit 9f674e48c13dcbc31ac903433727837795b81efe ]

Allocation of new_hash, inside xenvif_new_hash(), always happen
in softirq context, so use GFP_ATOMIC instead of GFP_KERNEL for new
hash allocation.
