[dm-devel] frozen mapped devices



Looks like domap() in multipath/main.c is not resuming a mapped device
before removing the
device in the event of an error returned from dm_addmap().  This results in
leaving the kernel
block_device structure for the mapped device remaining "frozen", so that
subsequent
attempts to reload corrected configuration data hang on the bd_mount_sem of
the block_device
since the instance of the mapped device structure holding the DMF_FS_LOCKED
flag bit
had been destroyed.
