Issue #2543 has been updated by swildner.

POSIX has this to say about EINVAL and EBUSY:

The directory to be removed is currently in use by the system or some process and the implementation considers this to be an error.

The path argument contains a last component that is dot.

So I think that we should actually return EBUSY instead of EINVAL for the attempt to rmdir() a directory that is a mount point.

Also, I'm not sure if we handle the "last component that is dot" case correctly yet.

Bug #2543: man rmdir(2) : add EINVAL to the error section

Author: jorisgio
Status: New
Priority: Normal
Target version: 

rmdir can return EINVAL if the directory is a mount point :

See sys/kern/vfs_syscalls.c:3997

         * Do not allow directories representing mount points to be
         * deleted, even if empty.  Check write perms on mount point
         * in case the vnode is aliased (aka nullfs).
        if (nd->nl_nch.ncp->nc_flag & (NCF_ISMOUNTPT))
                return (EINVAL);
