5Subject: [PATCH 1/5] Fill missing devices so degraded filesystems can be read
6
7When a device is missing, the btrfs tools need to be able to read alternate
8copies from the remaining devices. This creates placeholder devices
9that always return -EIO so the tools can limp along.

5Subject: [PATCH 2/5] Check for RAID10 in set_avail_alloc_bits
6
7When raid is setup with mkfs, it is supposed to cow the initial filesystem
8it creates up to the desired raid level. RAID10 was not in the list
9of RAID levels it checked for, so the initial FS created for RAID10
10actually only lived on the first disk.
11
12This works well enough because all the roots get quickly cowed during the
13first mount. The exception is the data relocation tree, which only gets
14cowed when we do a balance.
