Hi all,
this series tries to sort out accumulated mess around the name_to_dev_t
function. This function is intended to allow looking up the dev_t of a
block device based on a name string before the root file systems is
mounted and thus the normal path based lookup is available.
Unfortunately a few years ago it managed to get exported and used in
non-init contexts, leading to the something looking like a path name
also beeing lookuped up by a different and potential dangerous
algorithm.
This series does a fair amount of refactoring and finally ends up with
the renamed and improved name_to_dev_t only beeing available for the
early init code again.
The series is against Jens' for-6.5/block tree but probably applies
against current mainline just fine as well.
