OK, I have to do some outings: I am new to FreeBSD, and worse: I am
management (sort of rond-de-cuir).

What do I have to do as user root in a FreeBSD 15.0 installation to
update to 15.0-STABLE to get working FATTR4_CASE_INSENSITIVE and
FATTR4_CASE_PRESERVING support in FreeBSD NFS server?

Also, which FreeBSD commit added support for working
FATTR4_CASE_INSENSITIVE and FATTR4_CASE_PRESERVING?
