From 5b130948d53ae8fe426e8a0af725a634d972739f Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Tue, 19 Dec 2023 18:09:18 +0900 Subject: [PATCH] nilfs2: add missing set_freezable() for freezable kthread The kernel thread function nilfs_segctor_thread() invokes the try_to_freeze() in its loop. But all the kernel threads are non-freezable by default. So if we want to make a kernel thread to be freezable, we have to invoke set_freezable() explicitly.
