From e86d4cc55f9fd05092bad404c9c0d2ae2792ebab Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 11 Oct 2010 21:15:11 +0200 Subject: [PATCH] rbd: passing wrong variable to bvec_kunmap_irq() We should be passing "buf" here insead of "bv". This is tricky because it's not the same as kmap() and kunmap(). GCC does warn about it if you compile on i386 with CONFIG_HIGHMEM.
