Subject: [PATCH] module_arch_cleanup()
Date: Thu, 8 May 2003 18:41:17 +0200	[thread overview]
Message-ID: <20030508184117.A26726@lst.de> (raw)

IA64 needs to be able to hook into module unloading to get rid of
the unwind tables for modules.  (The actual implementation already
is in arch/ia64/kernel/module.c, David just seems to be to shy to
submit core changes :))
