From 7ae077802c9f12959a81fa1a16c1ec2842dbae05 Mon Sep 17 00:00:00 2001 From: Dave Chinner <dchinner@redhat.com> Date: Mon, 20 May 2013 09:51:16 +1000 Subject: [PATCH] xfs: remote attribute lookups require the value length When reading a remote attribute, to correctly calculate the length of the data buffer for CRC enable filesystems, we need to know the length of the attribute data. We get this information when we look up the attribute, but we don't store it in the args structure along with the other remote attr information we get from the lookup. Add this information to the args structure so we can use it appropriately.
