Subject: [PATCH] Force same size of struct autofs_v5_packet on x86 and x86_64
Date: Fri, 16 Sep 2011 12:06:38 +0200 [thread overview]
Message-ID: <1316167604.6545.84.camel@localhost.localdomain> (raw)
[-- Attachment #1: Type: text/plain, Size: 764 bytes --]
autofs_v5_packet is 300 bytes on x86 and 304 bytes on x86_64.
This difference is wrong and leads to a hang in systemd when running
a x86 userspace on an x86_64 kernel.
