Re: [PATCH 1/4] fanotify: Shrink struct fanotify_event_metadata by 32 bits

[Alexey Zaytsev <alexey.zaytsev@gmail.com>]

Hi, Eric. Sorry for the noise, but could you please comment at this
one? Because if it goes, it needs to go soon, before the .37 release,
or we won't be able change the ABI.

The other patches in the series are clearly not .37 material, so no
problem if you can't look at them right now.
