[LTP] [PATCH 1/4] readlinkat: Remove readlinkat fallback definition

[Petr Vorel]

Hi Yang,

Again, as I mentioned in v2 renameat() patch [1], the real reason for this lapi
function was IMHO missing glibc wrapper.  The correct git commit message should
have been glibc wrapper was added in ...

Also, without kernel support the function would not work at all, therefore it is
irrelevant when readlinkat was added into kernel. That applies to all git commit
messages. Due me merged v2 renameat() first, this is not applicable (patch must
be modified, I'm sorry).

This particular patch would deserve to note that since these 2 commits the lapi
is not even used (both released in 20230929 - a proof it can be really deleted):

0959b893a ("syscalls/readlinkat01: Convert to new API")
bcafe2971 ("syscalls/readlinkat02: Convert to new API")

Kind regards,
Petr
