From 36282881a795cbf717aca79392ae9cdf0fef59c9 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Sat, 8 Feb 2020 19:16:39 -0700 Subject: io-wq: add io_wq_cancel_pid() to cancel based on a specific pid Add a helper that allows the caller to cancel work based on what mm it belongs to. This allows io_uring to cancel work from a given task or thread when it exits.
