Subject: [PATCH 0/2] virtio: add gfp_t parameter to add_buf
Date: Thu, 29 Apr 2010 17:26:31 +0300	[thread overview]
Message-ID: <cover.1272549641.git.mst@redhat.com> (raw)

We need to allocate memory to post indirect buffers,
and sometimes drivers do this from a thread context,
so it helps to pass in a gfp_t parameter.

To avoid churn changing all drivers, add a new API
with a _gfp prefix, and make the old call lacking
gfp_t an inline wrapper.
