8b26a007b1 misc bcache fixes from ejt 2018-04-20 11:22:47 -05:00

a7cb76ae94 scan: use bcache for label scan and vg read 
New label_scan function populates bcache for each device
on the system.

The two read paths are updated to get data from bcache.

The bcache is not yet used for writing.  bcache blocks
for a device are invalidated when the device is written.
