Subject: RDMA/ucma: Avoid sending reject if backlog is full
X-Git-Tag: v2.6.21-rc4~79^2~1
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3492856e33da734501f2bdd8656cbfdf61f60330;p=linux-2.6

RDMA/ucma: Avoid sending reject if backlog is full

Change the returned error code to ENOMEM if the connection event
backlog is full.  This prevents the ib_cm from issuing a reject
on the connection, which can allow retries to succeed.
