Sebastian Andrzej Siewior 9fdcd0038b module: Extend the preempt disabled section in dereference_symbol_descriptor(). ... [ Upstream commit a145c848d69f9c6f32008d8319edaa133360dd74 ] dereference_symbol_descriptor() needs to obtain the module pointer belonging to pointer in order to resolve that pointer. The returned mod pointer is obtained under RCU-sched/ preempt_disable() guarantees and needs to be used within this section to ensure that the module is not removed in the meantime. Extend the preempt_disable() section to also cover dereference_module_function_descriptor(). Fixes: 04b8eb7a4c ("symbol lookup: introduce dereference_symbol_descriptor()") Cc: James E.J.
