Subject: ocfs2: Pack vote message and response structures
X-Git-Tag: v2.6.23-rc8~14^2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=813d974c53a2b353566a86bb127625b403696dae;p=linux-2.6

ocfs2: Pack vote message and response structures

The ocfs2_vote_msg and ocfs2_response_msg structs needed to be
packed to ensure similar sizeofs in 32-bit and 64-bit arches. Without this,
we had inadvertantly broken 32/64 bit cross mounts.
