On older Linux kernels (I tested on 4.4, corresponding to Ubuntu 16.04), opening a symlink using O_DIRECTORY | O_NOFOLLOW returns ELOOP instead of ENOTDIR. We should handle it the same, since a symlink is still not a directory and needs to be unlinked.

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with r? rust-lang/libs-api @rustbot label +T-libs-api -T-libs to request review from a libs-api team reviewer. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

@rustbot rustbot added the T-libs Relevant to the library team, which will review and decide on the PR/issue. label Apr 20, 2022

According to https://man7.org/linux/man-pages/man2/open.2.html, ELOOP is a valid return value for O_NOFOLLOW, so this seems fine (I guess in later versions O_DIRECTORY overrides this).
