Subject: [PATCH v2 0/2] guarantee natural alignment for kmalloc()
Date: Mon, 26 Aug 2019 13:16:25 +0200	[thread overview]
Message-ID: <20190826111627.7505-1-vbabka@suse.cz> (raw)

After a while, here's v2 of the series, also discussed at LSF/MM [1].
I've updated the documentation bits and expanded changelog. Also measured
effect on SLOB, and found it to be within noise. That required first adding
some accounting for SLOB, which I believe is useful in general, so that
became Patch 1. All other details are in Patch 2 changelog.
