Hi, This series adds new APIs to support btrfs scrub, balance, rescue and inspect. Some of them don't have tests because: - btrfs_scrub and btrfs_balance completes too early before we can test btrfs_scrub_cancel, btrfs_scrub_resume, btrfs_scrub_status, btrfs_balance_pause, btrfs_balance_cancel, btrfs_balance_resume and btrfs_balance_status. - can't determine a valid logical address for test btrfs_ins...

This series adds an initial implementation for scrub. It works quite straightforward. The usermode issues an ioctl for each device in the fs. For each device, it enumerates the allocated device chunks. For each chunk, the contained extents are enumerated and the data checksums fetched. The extents are read sequentially and the checksums verified. If an error occurs (checksum or EIO), a good copy
