The commit message is incomplete rather than misleading.  The problem
has been there for a long time but hasn't affected cdrom so not many
people have noticed it.  The changes to media revalidation exposed the
bug for cdrom too, so it became a regression for 2.6.38.  Please refer
to the following thread.

  https://lkml.org/lkml/2011/3/31/436

As the root cause was the same as the 2009 bug, I just referenced that
one.  I should have included the link to the newer thread or explained
how it affected recent conversion from ->media_changed to
->check_events.  My bad.

The patch was posted Apr 6th.  It somehow took quite long to reach
your tree.  Sorry about that too.

As for the warning message, I think it wouldn't be harmful but at -rc7
I'm a bit nervous too.  I'll take a deeper look.

Thank you.
