Hi Greg and stable team,
Here's a backport of relocation fixes that went into 5.16 aimed at the 5.15.x series of stable kernels. It's a problem people are currently running into when using btrfs on a zoned block device.
The following patches have been backported: 960a3166aed0 ("btrfs: zoned: allow preallocation for relocation inodes") 2adada886b26 ("btrfs: check for relocation inodes on zoned btrfs in should_nocow") e6d261e3b1f7 ("btrfs: zoned: use regular writes for relocation") 35156d852762 ("btrfs: zoned: only allow one process to add pages to a relocation inode") c2707a255623 ("btrfs: zoned: add a dedicated data relocation block group") 37f00a6d2e9c ("btrfs: introduce btrfs_is_data_reloc_root")
The backport has seen the usual regression testing with xfstests.
Now queued up, thanks.
