Subject: [PATCH] IB/rxe: double free on error
Date: Wed, 8 Mar 2017 08:21:52 +0300 [thread overview]
Message-ID: <20170308052152.GA31503@mwanda> (raw)
"goto err;" has it's own kfree_skb() call so it's a double free. We
only need to free on the "goto exit;" path.
Fixes: 8700e3e7c485 ("Soft RoCE driver")
