Subject: [PATCH] IB/mthca: Fix posting work requests to shared receive queues
X-Git-Tag: v2.6.14-rc3~150^2~4
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=3853194c2e174cee4da093c67bd54cbf9a38559a;p=linux-2.6-omap-h63xx.git

[PATCH] IB/mthca: Fix posting work requests to shared receive queues

The error handling paths in mthca_tavor_post_srq_recv() and
mthca_arbel_post_srq_recv() are quite bogus, the result of a
screwed up merge.  Fix them so they work as intended.
