Subject: [PATCH bpf 0/3] BPF LRU map fix

This set fixes LRU map eviction in combination with map lookups out
of system call side from user space. Main patch is the second one and
test cases are adapted and added in the last one. Thanks!

Daniel Borkmann (3):
  bpf: add map_lookup_elem_sys_only for lookups from syscall side
  bpf, lru: avoid messing with eviction heuristics upon syscall lookup
  bpf: test ref bit from data path and add new tests for syscall path
