From 3fedb3c5a80595d94f7cbe47a6dba9184d869eb8 Mon Sep 17 00:00:00 2001 From: Tom Tucker Date: Tue, 11 Mar 2008 14:31:40 -0400 Subject: SVCRDMA: Fix erroneous BUG_ON in send_write The assertion that checks for sge context overflow is incorrectly hard-coded to 32. This causes a kernel bug check when using big-data mounts. Changed the BUG_ON to use the computed value RPCSVC_MAXPAGES. Signed-off-by: Tom Tucker Signed-off-by: J.
