Subject: [PATCH] btrfs: Add support for new RAID1C34 profiles
|
|
|
|
New 3- and 4-copy variants of RAID1 were merged into Linux kernel 5.5.
|
|
Add the two new profiles to the list of recognized ones. As this builds
|
|
on the same code as RAID1, only the redundancy level needs to be
|
|
adjusted, the rest is done by the existing code.
