[LTP] [PATCH v1 1/3] fsetxattr02: Adapt test for kernel 7.0+ socket xattr support

[Petr Vorel]

Hi Jan,

> Starting with kernel 7.0.0, sockets support extended attributes in the
> user.* namespace. This behavior was enabled by dc0876b9846d ("xattr: support
> extended attributes on sockets"), which permits user.* xattrs on S_IFSOCK
> inodes (previously rejected with -EPERM).

Good catch, thanks!

very nit: The commit is obvious. If anything to add, I would add the git hash itself.

Kind regards,
Petr
