This series fixes the potential problem of autofs returning ELOOP when
a mount exists in a propogation private mount namespace other than the
namespace in which the mount is to be performed.
I'm posting the series as an RFC in the hope of catching stupid mistakes
that I may have made before submitting to mmotm. Please note the series
here is against the current Linus tree and may be slightly different when
posted for inclusion in mmotm.
Please review and post any comments.
