Subject: [patch 2/2] xprtrdma: checking for NULL instead of IS_ERR()
Date: Thu, 05 Nov 2015 08:39:52 +0000	[thread overview]
Message-ID: <20151105083952.GB19405@mwanda> (raw)

The rpcrdma_create_req() function returns error pointers or success.  It
never returns NULL.

Fixes: f531a5dbc451 ('xprtrdma: Pre-allocate backward rpc_rqst and send/receive buffers')
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
