As of now there is no good way (like api) to check that.
A workaround way is to check if the O_EXCL open is unsuccessful.
This is safe since otherwise the BTRFS_IOC_SCAN_DEV ioctl would
fail if the disk-path can not be opened with the
This patch is replaced By:
btrfs-progs: avoid ioctl for multipath-dev with its non-multipath path
which is also sent to this mailing list.
