A new stable release of dm for 2.4.20 is available:
Give each device its own io mempool to avoid a potential
deadlock with stacked devices. [HM + EJT]
Let the persistent/non persistent arg to the snapshot constructor
be case insensitive. [Heinz Mauelshagen]
queue_io() was checking the DMF_SUSPENDED flag rather than the new
DMF_BLOCK_IO flag. This meant suspend could deadlock under load.
dm_suspend(): Stop holding the read lock around the while loop that
waits for pending io to complete.
Add a run_task_queue(&tq_disk) to encourage pending io to flush
when we're doing a dm_suspend().
