Subject: [PATCH] tomoyo: don't special case PF_IO_WORKER for PF_KTHREAD
Date: Thu, 25 Mar 2021 18:44:13 -0600 [thread overview]
Message-ID: <46f6e3cb-cc96-d214-e183-71dd238da075@kernel.dk> (raw)
The io_uring PF_IO_WORKER threads no longer have PF_KTHREAD set, so no
need to special case them for credential checks.
