I've been doing some more testing on it, and while I can get a 25%
reduction in the time to create and remove 10 million inodes with
per-sb shrinker, I can't get the reclaim pattern stable enough for
my liking.

At this point in the cycle, I'd much prefer just to go with adding a
context to the shrinker API to fix the XFS locking issues (i.e. the
original patches I sent) and spend a bit more time working out which
combination of Nick's and my bits that improves reclaim speed whilst
retaining the stability of the courrent code....
