Subject: [PATCH RFC 0/3] drivers/char: remove /dev/kmem for good
Date: Fri, 19 Mar 2021 15:34:49 +0100 [thread overview]
Message-ID: <20210319143452.25948-1-david@redhat.com> (raw)
Let's start a discussion if /dev/kmem is worth keeping around and
fixing/maintaining or if we should just remove it now for good.
More details / findings in patch #1. Patch #2 and #3 perform minor cleanups
based on removed /dev/kmem support.
Only compile-tested on x86-64 -- good enough for discussing the general
topic (RFC).
David Hildenbrand (3):
drivers/char: remove /dev/kmem for good
mm: remove xlate_dev_kmem_ptr()
mm/vmalloc: remove vwrite()
