The patch titled
ext3 -nobh option causes oops
has been removed from the -mm tree. Its filename is
ext3-nobh-option-causes-oops.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ext3 -nobh option causes oops
From: Badari Pulavarty <pbadari@xxxxxxxxxx>
For files other than IFREG, nobh option doesn't make sense. Modifications
to them are journalled and needs buffer heads to do that. Without this
patch, we get kernel oops in page_buffers().
