Subject: Re: [PATCH v3 09/12] man/man2/open_tree.2: document "new" mount API

man open_tree says:

It seems this is wrong, because this commit exists: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=06b1ce966e3f8bfef261c111feb3d4b33ede0cd8 .
I'm not sure about this. (I didn't test this.)
