Message-ID: <1314078115-8121-2-git-send-email-sathya.perla@emulex.com> Date: Tue, 23 Aug 2011 11:11:51 +0530 From: Sathya Perla <sathya.perla@...lex.com> To: <netdev@...r.kernel.org> Subject: [PATCH net-next 1/5] be2net: Fix race in posting rx buffers. There is a possibility of be_post_rx_frags() being called simultaneously from both be_worker() (when rx_post_starved) and be_poll_rx() (when rxq->used is 0). This can be avoided by posting rx buffers only when some completions have been reaped.
