Subject: [PATCH 138/138] Btrfs-progs: bugfix for scrubbing single devices
|
|
|
|
Scrub can be invoked to scrub only a single device of a (mounted) filesystem.
|
|
The code determines whether the given path is a mountpoint of a filesystem
|
|
by issueing a btrfs-specific ioctl to it. Only in case of EINVAL it assumed
|
|
it may be a device, all other errnos just caused it fail, but some devices
|
|
(correctly) return ENOTTY. This patch adds this to the error check.
