Subject: [PATCH 0/2] introduce DUMP_PREFIX_UNHASHED for hex dumps
Date: Sat, 16 Jan 2021 16:09:48 -0600 [thread overview]
Message-ID: <20210116220950.47078-1-timur@kernel.org> (raw)
First patch updates print_hex_dump() and related functions to
allow callers to print hex dumps with unhashed addresses. It
adds a new prefix type, so existing code is unchanged.
Second patch changes a page poising function to use the new
address type. This is just an example of a change. If it's
wrong, it doesn't need to be applied.
IMHO, hashed addresses make very little sense for hex dumps,
which print addresses in 16- or 32-byte increments. Typical
use-case is to correlate an addresses in between one of these
increments with some other address, but that can't be done
if the addresses are hashed. I expect most developers to
want to replace their usage of DUMP_PREFIX_ADDRESS with
DUMP_PREFIX_UNHASHED, now that they have the opportunity.
