[dm-devel] [PATCH 0/2] Add suspended state check for target messages



This patch adds a accessor function that allows determining if a
mapped_device is in the suspended state and then adds this check to the
multipath targets multipath_message function.

As previously described in the email at the archive url provided below the
target_message ioctl can call into the target after suspend completes.
This can cause new work to be queued and actions to be taken by the target
that should be prevented in the suspended state.
