Subject: [PATCH 0/8] mm/slub: Add SLUB_RANDOMIZE support
Date: Sun, 13 Mar 2011 20:20:44 -0400 [thread overview]
Message-ID: <20110316022804.27676.qmail@science.horizon.com> (raw)
As a followup to the "[PATCH] Make /proc/slabinfo 0400" thread, this
is a patch series to randomize the order of object allocations within
a page. It can be extended to SLAB and SLOB if desired. Mostly it's
for benchmarking and discussion.
It Boots For Me(tm).
Patches 1-4 and 8 touch drivers/char/random.c, to add support for
efficiently generating a series of uniform random integers in small
ranges. Is this okay with Herbert & Matt?
I did a bit of code cleanup while I was at it, but kept it to separate
patches. Patches 4 and 7 are the heart of the new code, but I'd
particularly like comments on patch 8, as I don't understand the kconfig
stuff very well. Is the feature description good and are the control
knobs adequate?
Checkpatch complains about a too-short CONFIG option description on
8/8; I think it's spurious.
