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.gb27...@order.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.
