[PATCH bpf-next v1 0/3] Use kmalloc_nolock() universally in BPF local storage

[Amery Hung <ameryhung@gmail.com>]

Socket local storage did not convert to use kmalloc_nolock() since there
were observable performance degredation due to kfree_nolock() hitting the
slow path and the lack of kfree_rcu()-like batching freeing. Now that
these concern were addressed in slub, convert all remaining local storage
flavors to use kmalloc_nolock().


Amery Hung (3):
  selftests/bpf: Remove kmalloc tracing from local storage create bench
  bpf: Use kmalloc_nolock() universally in local storage
  bpf: Remove gfp_flags plumbing from bpf_local_storage_update()
