Subject: [PATCH v1 0/1] perf: High-order AUX allocations
Date: Fri, 15 Feb 2019 13:47:26 +0200	[thread overview]
Message-ID: <20190215114727.62648-1-alexander.shishkin@linux.intel.com> (raw)

Hi Peter,

This supersedes [1]. Since there is no reason not to always go with high
order allocations, we simply change the AUX allocator to optimistically
do that with a fallback to lower orders. And since this is not an opt-in
any more, no tool changes.
