From 777a71dd4d901f055967ddbd038d2a74ffce0eb8 Mon Sep 17 00:00:00 2001 From: Erez Zilber Date: Mon, 11 Sep 2006 12:19:17 +0300 Subject: [PATCH] IB/iser: fix a check of SG alignment for RDMA dma mapping may include a "compaction" of the sg associated with scsi command. Hence, the size of the maximal prefix of the SG which is aligned for rdma must be compared against the length of the dma mapped sg (mem->dma_nents) and not against the size of it before it was mapped (mem->size).
