Last time we have discussed this with Oleg, he said, that there are lots
of stuff relying on the fact, that bkl can be acquired many times by the
same process. And simple replacing bkl by per-superblock lock makes life
just horrible ;)

There something like bkl but per-superblock based is needed. Or lots of
code should be changed, which is not good idea.

But anyway, this should be done one day, and if I have free time
(probably vacation) and it will not be done until that time, I'd like to
work on it along with Oleg and you ;)
