From 97c18e2c7a8e36d2d83d50ee070314aadac73a11 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 9 Apr 2009 10:35:47 +0800 Subject: module: try_then_request_module must wait Since the whole point of try_then_request_module is to retry the operation after a module has been loaded, we must wait for the module to fully load. Otherwise all sort of things start breaking, e.g., you won't be able to read your encrypted disks on the first attempt.
