[PATCH v2 3/4] dax/bus.c: Don't use down_write_killable for non-user processes
From: Vishal Verma
Date: Tue Apr 16 2024 - 17:47:49 EST
Change an instance of down_write_killable() to a simple down_write() where
there is no user process that might want to interrupt the operation.
Fixes: c05ae9d85b47 ("dax/bus.c: replace driver-core lock usage by a local rwsem")
