+++ This bug was initially created as a clone of Bug #209843 +++ RHEL 4.5 clone When suspending a device-mapper device, dm_suspend() sleeps until all necessary I/O is completed. This state is triggered by a callback from persistent_commit(). But some I/O can still be issued *after* the callback (to prepare the next metadata area for use if the current one is full). This patch delays the callback until after that I/O is complete.
