btrfs: preallocate radix tree node for readahead We can preallocate the node so insertion does not have to do that under the lock. The GFP flags for the per-device radix tree are initialized to GFP_NOFS & ~__GFP_DIRECT_RECLAIM but we can use GFP_KERNEL, same as an allocation above anyway, but also because readahead is optional and not on any critical writeout path.
