[PATCH -perfbook 0/8] May 2026 updates (1st set)

Hi Paul,

I guess this is larger than what you have expected.
I didn't expect it, either.  :-/

Patch 1/8 is the usual update.  I see there were some cleanups in
RCU code but would like to defer text updates to you.

Patch 2/8 takes care of a regression in cleveref.  It started affecting
perfbook as early as Debian 13, which I failed to catch ...

There's been quite a few other issues in early testing under
Ubuntu 26.04 and Fedora 44.

Ubuntu 26.04 misses an update of lineno.sty dated in March 2026.
Debian has updated TeX Live packages under testing, and hopefully,
Ubuntu 26.04 will follow suit soon.

One of Fedora 44's issue looks more concerning. Please have a look
at Patch 5/8 changelog.

FAQ-BUILD.txt and files under docker/ want further updates, but I'd like
to see how long those issues in distro packages remain.

Thanks, Akira
