Dynamic debug doesn't have a bitmask function and
still requires looking through the code for lines
and format strings.

I think you are looking for a system wide equivalent
for the ethtool/netif_<level> mechanism.

Nothing like that exists currently.

Some code uses a bitmask/and, other code uses a
level/comparison.

Care to propose something?
