5 +0200 blkcg: __blkg_lookup_create() doesn't need radix preload There's no point in calling radix_tree_preload() if preloading doesn't use more permissible GFP mask. Drop preloading from __blkg_lookup_create(). While at it, drop sparse locking annotation which no longer applies. v2: Vivek pointed out the odd preload usage. Instead of updating, just drop it.
