I've just spotted something that all these things have in common.  The old
cookie has FSCACHE_COOKIE_RELINQUISHING set in the flags (fl=222).  I don't
have a wait for this situation in fscache - which I should.

Interestingly, '020001bdc0a80064' looks like is could be the key from the
server level, assuming this is from NFS:

	0200 01bdc0a8 0064

could be:

	AF_INET (LE), 1.189.192.168, 100 (BE)
