The idea was to introduce /dev/mapper to find for btrfs disk,

dev scan use the disks scan they do it on their own.
So here it would congregate btrfs-disk scans at the function
scan_devs_for_btrfs, adds /dev/mapper to be used to scan
for btrfs, and updates its calling functions and few bug fixes.
Just scan /dev/block/*. That contains all block devices.
That does not help. /dev/mapper has unified dev path,
/dev/block/ don't. when multipath is enabled for a disk,
we don't have to bother to probe its non multipath block
path. using /dev/mapper helps in this context.
Thanks
