Subject: [PATCH 0/2] rcutorture: Some PREEMPT_RT fixlets
Date: Tue, 3 Aug 2021 23:54:35 +0100 [thread overview]
Message-ID: <20210803225437.3612591-1-valentin.schneider@arm.com> (raw)
Hi folks,
I've been meaning to run RCU torture under v5.13-rt1 to validate my hacking
around the RCU offloaded state [1], but have hit some warnings.
The second patch clearly isn't a thing of beauty, but FWIW it lets me run RCU
torture tests without any extra steps.
As mentioned over IRC, this started as a .setup() callback for the kosftirqd
threads gated behind CONFIG_RCU_BOOST && CONFIG_RCU_TORTURE_TEST, but I figured
keeping RCU torture specific stuff within rcutorture.c would be a tad smarter.
I hate either version, but here it is regardless.

Cheers,
Valentin
