Funlinkat

There is a thread about this in Linux here https://bugzilla.kernel.org/show_bug.cgi?id=93441

OP suggests adding AT_EMPTY_PATH support to unlinkat, question is whether an fd refers to a path after it is opened.

The mind boggles at what a sanitary check could be, but the article keeps talking about them instead of sanity checks.

F·unlink·at ;)
