ilog2() defined in include/linux/log2.h

And you have MAX_ERROR in one comment, instead of MAX_ERRNO :-)

"could", not "should".  I think it is agreed that this is a good
idea, is it?

I would rather this was a wb_err_t or similar, and that the functions
which implement it take a pointer to a wb_err_t.
Then the 'error' in 'struct nfs_open_context' could become a 'wb_err_t',
and nfs could use these functions to do error tracking the way it wants
to.

Thanks - looking good.
