From 3a200911ada2d5b955c2c6daa22364c6de83c52c Mon Sep 17 00:00:00 2001 From: Tejun Heo <tj@kernel.org> Date: Wed, 9 Mar 2011 19:54:28 +0100 Subject: [PATCH] xsysace: Convert to bdops->check_events() Convert from ->media_changed() to ->check_events(). xsysace buffers media changed state and clears it on revalidation. It will behave correctly with kernel event polling.
