Backport request: liburcu and libblkid

Hello Debian Backports Team,

I would like to request the backporting of liburcu and libblkid to Debian
Bookworm.

   - liburcu is available as liburcu8t64 in Trixie and Sid (version 0.14.1).
   https://packages.debian.org/search?keywords=liburcu8t64
   - libblkid version 2.40.4-1 exists in Trixie, and 2.40.4-2 in Sid.
   https://packages.debian.org/trixie/libblkid-dev


I have successfully rebuilt the source package for liburcu8t64 in a
Bookworm environment after downgrading the dpkg-dev build-requirement.
However, during installation, dpkg reported that liburcu8t64 (new) breaks
liburcu8, which is a dependency for several packages (e.g., xfsprogs,
glusterfs).
After installing it with --force, xfsprogs continued to function without
issues.
I don't know why liburcu8 change package name to liburcu8t64, maybe using
old name is safe for Bookworm.

Both of these packages are necessary for compiling bcachefs-tools in its
recent versions.

Would it be possible to have them backported to Bookworm?
Thank you for your time and consideration!

Best regards,
Krzysztof Hajdamowicz
