Modified files:
sys/vm device_pager.c
Log:
Protect the creation of the device pager with the dev_pager_mtx. Lookup
of device pager in the pagers list by handle is now synchronized with
its removal from the list, and dev_pager_mtx is put before vm object
lock in lock order. Dispose the dev_pager_sx lock, since dev_pager_mtx
now covers the same block.
