Date: Tue, 13 Jan 2009 10:56:20 +0000 [thread overview]
Message-ID: <1231844180.3580.0.camel@localhost.localdomain> (raw)

Subject: [PATCH] GFS2: Remove unused field from glock
The time stamp field is unused in the glock now that we are
using a shrinker, so that we can remove it and save sizeof(unsigned long)
bytes in each glock.
