[PATCH v5 0/4] Proposal to add eventfd option to --decode-fds

[Sahil Siddiq]

Hi,

I noticed that the most recent commit in strace (f62887c:
Post-release administrivia) adds the "noteworthy changes"
header in NEWS. Since commit #4 of v4 [1] also had this
change, I decided to revert my change and send a new
series.

I have also changed the subject header from "RFC PATCH"
to "PATCH".

Please let me know if more changes have to be made.

Thanks,
Sahil
