From 7104e2d5a85b4b786d6a63568beffe1e185547bb Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Wed, 4 Oct 2006 02:15:41 -0700 Subject: [PATCH] mmc: use own work queue The MMC layer uses the standard work queue for doing card detection. As this queue is shared with other crucial subsystems, the effects of a long (and perhaps buggy) detection can cause the system to be unusable. E.g. the keyboard stops working while the detection routine is running. The solution is to add a specific mmc work queue to run the detection code in. This is similar to how other subsystems handle detection (a full kernel thread is the most common theme).
