Subject: [PATCH 0/4] btrfs: fix relocation on RAID stripe-tree filesystems

When doing relocation on RST backed filesystems, there is a possibility of
a scatter-gather list corruption.

See patch 4 for details.

      btrfs: rename btrfs_io_stripe::is_scrub to rst_search_commit_root
      btrfs: set rst_search_commit_root in case of relocation
      btrfs: don't readahead the relocation inode on RST
