[LTP] [PATCH v5 0/5] Add fchmodat2 testing suite

Hi,

> fchmodat2_02 fails with EOPNOTSUPP because of missing feature.
> According to documentation, the feature has been implemented in
> kernel 6.6, but __in reality__ AT_SYMLINK_NOFOLLOW is not working
> on symbolic files. Also kselftests, which are meant to test the
> functionality, are not working and they are treating fchmodat2()
> syscall failure as SKIP. Please take a look at the following code
> before reviewing:

For anybody who did not follow the previous version, this has been discussed and
solved (visible in changelog below)

Kind regards,
Petr
