Hello,
Patch 1~6 cleans up & prepares for supporting ublk-bpf, which should be
ready to go.
Patch 7~14 supports ublk-bpf over struct_ops and selftests code. And
please see detailed motivation in commit log of "ublk: bpf: add bpf struct_ops"
and the last document patch.
Patch 15~21 adds bpf aio over struct_ops and applies it for ublk-bpf, and
selftests code.
Patch 22 adds document for ublk-bpf.
Git tree:
https://github.com/ming1/linux.git ublk_bpf_rfc
https://github.com/ming1/linux/commits/ublk_bpf_rfc/
Kernel selftest:
make -C tools/testing/selftests TARGETS=ublk run_tests
Comments are welcome!
