Merge tag 'bpf-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf

Pull bpf fixes from Alexei Starovoitov:

 - Replace bpf_map_kmalloc_node() with kmalloc_nolock() to fix kmemleak
   imbalance in tracking of bpf_async_cb structures (Alexei Starovoitov)

 - Make selftests/bpf arg_parsing.c more robust to errors (Andrii
   Nakryiko)

 - Fix redefinition of 'off' as different kind of symbol when I40E
   driver is builtin (Brahmajit Das)

 - Do not disable preemption in bpf_test_run (Sahil Chandna)

 - Fix memory leak in __lookup_instance error path (Shardul Bankar)

 - Ensure test data is flushed to disk before reading it (Xing Guo)
