blkcg: make root blkcg allocation use %GFP_KERNEL
Currently, blkcg_activate_policy() depends on %GFP_ATOMIC allocation from __blkg_lookup_create() for root blkcg creation. This could make policy fail unnecessarily. Make blkg_alloc() take @gfp_mask, __blkg_lookup_create() take an optional @new_blkg for preallocated blkg, and blkcg_activate_policy() preload radix tree and preallocate blkg with %GFP_KERNEL before trying to create the root blkg. v2: __blkg_lookup_create() was returning %NULL on blkg alloc failure instead of ERR_PTR() value. Fixed. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
