From 7b33dc2b050b71de0e202885a26caffbc864d072 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 14 Jun 2012 21:36:09 +0300 Subject: RDMA/ocrdma: Fix off by one in ocrdma_query_gid() The dev->sgid_tbl[] array is allocated in ocrdma_alloc_resources(). It has OCRDMA_MAX_SGID elements so the test here is off by one.
