Thanks for letting me know, as this led me to further testing that found 
some other kernel bugs in this area, possibly introduced by that kernel 
commit. Please see:

"flistxattr with right size wrongly fails with ERANGE, breaking 'cp -a' 
etc" <https://bugzilla.redhat.com/show_bug.cgi?id=2369561>

The email thread starting at "[PATCH] Fix listxattr-related races and 
stack overflows" 
<https://lists.nongnu.org/archive/html/acl-devel/2025-05/msg00003.html>.
