[PATCH 0/7] Readahead clenups

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I spotted some GFP_NOFS uses in readahead and converted them to GFP_KERNEL with
a few cleanups along the way.

David Sterba (7):
  btrfs: preallocate radix tree node for readahead
  btrfs: use simpler readahead zone lookups
  btrfs: preallocate radix tree node for global readahead tree
  btrfs: remove redundant parameter from btree_readahead_hook
  btrfs: remove redundant parameter from reada_find_zone
  btrfs: remove redundant parameter from reada_start_machine_dev
  btrfs: remove local blocksize variable in reada_find_extent
