This test only worked accidentially, and would
break once dirfd caching is added.
fs.Mkdir(..., "dir1/dir2", ...) is illegal
(child name cannot contain slashes).
Breaks mounting on MacOS: unix.Faccessat on Darwin does NOT (yet)
support AT_SYMLINK_NOFOLLOW. See d44fe89ba4f3252c5bd00c4f7730197732f2a26a .
This reverts commit 0805a63df1b5f915b228727f6074c2506922d0ad.
Bug looked like this:
$ ls -l .
total 0
drwxrwxr-x. 2 jakob jakob 60 Jan 3 15:42 foo
-rw-rw-r--. 1 jakob jakob 0 Jan 3 15:46 x
$ ls -l .
ls: cannot access '.': No such file or directory
(only happened when "" was in the dirCache)
This function is in all fastpaths, will get a cache, and needs
its own file.
