Subject: [PATCH 0/4] brd: sanity checks and dynamic ram disk creation/destroying

Hi!

While toying around with a library which needs small block devices for
quorum management, I came up with these patches to dynamically create
and destroy ram disks (I wanted to have non-swappable backed devices).

Feedback is appreciated!

Change log (since RFC patch <20121014024836.GB27966@...er.stressinduktion.org>):
1) module parameters(rd_nr, rd_size, max_part) are now unsigned ints
2) check for active users of ram disk before BLKFLSBUFing
3) switched from lists to idrs for device management

The patches apply against v3.6.
