Current release - regressions:
 
  - eth: fman: re-expose location of the MAC address to userspace,
    apparently some udev scripts depended on the exact value
 
 Current release - new code bugs:
 
  - bpf:
    - wait for busy refill_work when destroying bpf memory allocator
    - allow bpf_user_ringbuf_drain() callbacks to return 1

Finally, go back and read
:ref:`Documentation/process/submitting-patches.rst <submittingpatches>`
to be sure you are not repeating some common mistake documented there.
My company uses peer feedback in employee performance reviews. Can I ask netdev maintainers for feedback?
---------------------------------------------------------------------------------------------------------
Yes, especially if you spend significant amount of time reviewing code
and go out of your way to improve shared infrastructure.
The feedback must be requested by you, the contributor, and will always
be shared with you (even if you request for it to be submitted to your
manager).
