Aleksa, thank you! Don't give up. We all need these manpages.

I see you didn't address some my previous notes.

* move_mount(2) still says "Mount objects cannot be attached beneath the filesystem root".
I suggest saying "root directory" or "root" or "root directory of the process" or just "/"
instead. But you may keep this phrase as is, of course.

* Docs for FSPICK_NO_AUTOMOUNT in fspick(2) are still wrong. They say that FSPICK_NO_AUTOMOUNT
affects all components of path. Similar thing applies to mount_setattr(2) and move_mount(2)

* open_tree(2) still says:

If flags does not contain OPEN_TREE_CLONE, open_tree() returns a file descriptor
that is exactly equivalent to one produced by openat(2) when called with the same dirfd and path.

This is not true if automounts are involved. I suggest adding "modulo automounts". But you may
keep everything, of course.
