We use 1.04.00 at the moment and there was no glock_purge flag in it so
i checked the stable branch and found nothing. That HEAD and RHEL5 both
have the same "patchlevel" and only differ on the followed kernel
version was the reason for asking if this could be also made for RHEL4
and STABLE...

We'll wait for the 2.6.23 release before we migrate to 2.01.00.

I think a separate branch which follows the last released vanilla kernel
tree for gfs2 could be useful while there is so much movement in HEAD.
Merging HEAD into that branch after each merge window on Linus tree
could minimize the needed manpower and the release of tarballs would
also require less time out of that branch. Adopters of the tarball could
get fixes from there too. Before gfs2 the STABLE branch was exactly that
or wasn't it?
