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).
