Subject: [PATCH 05/35] Ignore the error ENXIO and ENOMEDIUM during a devs
scan
Ignore the error ENXIO (device don't exists) and ENOMEDIUM (
No medium found -> like a cd tray empty) in the function
btrfs_scan_one_dir.
This avoids spurios errors due to an empty CD or a block device node
without a device (which is frequent in a static /dev).
