[PATCH 0/4] Cleanups for mtd translation layer

From: Maxim Levitsky
Date: Fri Jan 22 2010 - 10:32:21 EST


I have broken up the patch series that I created for proper
SmartMedia/xD support.

This patch series contain patches that fix hotplug & suspend/resume in
mtd translation layer.

Patches are (almost) unmodified from last submission, and well tested on
real hotplugable card.
I can say that for a long time (even before last submission) I had no
issues regarding hotplug and/or suspend resume even in exterme cases.
(like suspending the system while doing 'dd if=/dev/zero of=/dev/smblka'
or yanking the card out while read or write is performed)

First two patches, prepare ground for real work and don't add new

Third patch adds everything needed to common translation layer to make
the hotplug work.

Last patch makes suspend/resume work much better by allowing to freeze
the IO thread, thus avoiding situation you suspend in middle of IO.

Best regards,
Maxim Levitsky
