jfs: Add missing set_freezable() for freezable kthread

ISCAS-Vulab · Sasha Levin · commit aeecd32724c5 · 2026-03-04T07:21:10.000-05:00
[ Upstream commit eb0cfcf ] The jfsIOWait() thread calls try_to_freeze() but lacks set_freezable(), causing it to remain non-freezable by default. This prevents proper freezing during system suspend. Add set_freezable() to make the thread freezable as intended.
