From e35afcf91230238dc27f98d1cd7cb787474b28cb Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Wed, 2 Sep 2020 12:44:20 -0600 Subject: [PATCH] io_uring: io_sq_thread() doesn't need to flush signals We're not handling signals by default in kernel threads, and we never use TWA_SIGNAL for the SQPOLL thread internally. Hence we can never have a signal pending, and we don't need to check for it (nor flush it).
