From a280c9ceeca73fad22af79b08b470fc7126cf1d5 Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Mon, 18 Dec 2023 13:23:23 +0800 Subject: jfs: Add missing set_freezable() for freezable kthread The kernel thread function jfs_lazycommit() and jfs_sync() invoke the try_to_freeze() in its loop. But all the kernel threads are no-freezable by default. So if we want to make a kernel thread to be freezable, we have to invoke set_freezable() explicitly.
