Subject: [PATCH 0/6] cifs: Use iov_iters down to the network transport
Date: Mon, 09 May 2022 17:36:06 +0100	[thread overview]
Message-ID: <165211416682.3154751.17287804906832979514.stgit@warthog.procyon.org.uk> (raw)


Hi Steve,

Here's a subset of my cifs-experimental branch.  It alters the cifs driver
to pass iov_iters down to the lowest layers where they can be passed to the
network transport.

I've fixed a couple of bugs in it also, including the RCU warning you were
seeing.  I'm seeing some slow calls, however, but I'm not sure how to debug
them.  RDMA also needs looking at, but I'm not sure how the RDMA API works.

I've pushed the patches here also:
