Subject: [PATCH 0/4] dma-pool: Fix atomic pool selection
Date: Thu,  9 Jul 2020 18:19:00 +0200	[thread overview]
Message-ID: <20200709161903.26229-1-nsaenzjulienne@suse.de> (raw)

This is my attempt at fixing one of the regressions we've seen[1] after
the introduction of per-zone atomic pools.

This combined with "dma-pool: Do not allocate pool memory from CMA"[2]
should fix the boot issues on Jeremy's RPi4 setup.
