Subject: [PATCH 0/2] Convert btrfs_root::delayed_nodes_tree to xarray
Date: Thu, 30 Nov 2023 23:49:06 +0100	[thread overview]
Message-ID: <cover.1701384168.git.dsterba@suse.com> (raw)

This restarts the radix-tree to xarray conversion that we had to revert.
There are two more structures to convert, possibly with also spinlock to
mutex conversions needed (buffer_radix and fs_roots_radix), but for the
buffer radix I don't want to do now as we have the folio conversion
ongoing. The fs_roots will most likely need the lock conversion so
that's a change that I want to take the whole dev cycle, planned for 6.9.

David Sterba (2):
  btrfs: drop radix-tree preload from btrfs_get_or_create_delayed_node()
  btrfs: use xarray for btrfs_root::delayed_nodes_tree instead of
    radix-tree
