Hi,

The patch set is just a bundle of fixes. Patch #1 fixes the out-of-bound
for sockmap link fdinfo. Patch #2 fixes the kmemleak report when parsing
the mount options for bpffs. Patch #3~#7 fix issues related to bits
iterator.

Please check the individual patches for more details. And comments are
always welcome.

Hou Tao (7):
  bpf: Add the missing BPF_LINK_TYPE invocation for sockmap
  bpf: Preserve param->string when parsing mount options
  bpf: Free dynamically allocated bits in bpf_iter_bits_destroy()
  bpf: Check the validity of nr_words in bpf_iter_bits_new()
  bpf: Change the type of unsafe_ptr in bpf_iter_bits_new()
  selftests/bpf: Test multiplication overflow of nr_bits in bits_iter
  selftests/bpf: Pass a pointer of unsigned long to bpf_iter_bits_new()
