Subject: [RFC 00/11] select_idle_sibling rework
Date: Wed, 30 May 2018 16:22:36 +0200
Message-ID: <> (raw)

Hi all,

This is all still very preliminary and could all still go up in flames (it has
only seen hackbench so far). This is mostly the same code I posted yesterday,
but hopefully in a more readable form.

This fixes the SIS_PROP as per the outline here:

and Rohit's suggestion of folding the iteration loops.

For testing I would suggest to ignore the last 3 patches, those are purely
cleanups once the first lot is found to actually work as advertised.
