Subject: [PATCH] Oracle startup split_vma fix
Date: Tue, 1 Oct 2002 16:32:35 +0100 (BST) [thread overview]
Message-ID: <Pine.LNX.4.44.0210011621490.1203-100000@localhost.localdomain> (raw)
In-Reply-To: <dny99icwp0.fsf@magla.zg.iskon.hr>
Alessandro Suardi and Zlatko Calusic independently reported that
Oracle cannot start on recent 2.5: excellent research by Zlatko
quickly pointed to vm_pgoff buglet in the new split_vma.
Patch below against 2.5.40 or 2.5.40-mm1: please apply.
