Please please no. These should not be needed by anything.
And if they really do, they must be EXPORT_SYMBOL_GPL().

Thanks. I was indeed skeptical about submitting this particular change.
Do you think it's more acceptable if I implement a for_each_blk() helper
(cf. patch 2 on this series) on block code?
I couldn't find any other way to do this (get all block devices on the
system), so please let me know if I missed something.
Cheers,
Enzo
