Subject: [PATCH 00/23] sched: Remove FIFO priorities from modules
Date: Wed, 22 Apr 2020 13:27:19 +0200 [thread overview]
Message-ID: <20200422112719.826676174@infradead.org> (raw)
After having seen yet another patch that adds a FIFO kernel thread at a random
priority, I bit the bullet and implemented the suggestion done a while ago:
Flat out remove the ability to set a specific FIFO priority
As argued in the patches themselves, the kernel has no clue what actual
priority it should use for various things, so it is useless (or worse, counter
productive) to even try.
