Hello Olivier,

this proposed update breaks two dependent packages,
  bcachefs-tools and bcachefs-tools-minimal-static.
Could you maybe have a look?

Hi,

I've had a look at `bcachefs-tools'.  It seems to me that the problem is
upstream and not related to userspace-rcu itself.  Developers of
`bcachefs-tools' seem to use the returned value of `uatomic_set', which
was expanding to `CMM_STORE_SHARED', which does indeed return a value.
However, in lattest version of URCU, we've changed the expansion of
`uatomic_set' to something else that does not return any value.

It is documented that the signature of `uatomic_set' is:

  void uatomic_set(type *addr, type v);


We can either bump the version of bcachefs-tools to latest commit or
keep a second version of urcu.

What do you think?

actually bcachefs-tools is far from its latest version:
We are on 1.11.0 from about a year ago, and there is a 1.25.3 from
two weeks ago. Maybe you could try updating it first?

Notice that most of the project development has moved to codeberg:
   https://codeberg.org/guix/guix ,
in case submitting a pull request there suits you better.

Otherwise we are still looking at debbugs for the next few months.

Andreas
