autofs - remove obsolete d_invalidate() from expire
Biederman's umount-on-rmdir series changes d_invalidate() to sumarily remove mounts under the passed in dentry regardless of whether they are busy or not. So calling this in fs/autofs4/expire.c:autofs4_tree_busy() is definitely the wrong thing to do becuase it will silently umount entries instead of just cleaning stale dentrys. But this call shouldn't be needed and testing shows that automounting continues to function without it. As Al Viro correctly surmises the original intent of the call was to perform what shrink_dcache_parent() does. If at some time in the future I see stale dentries accumulating following failed mounts I'll revisit the issue and possibly add a shrink_dcache_parent() call if needed.
