o Ok, this seems to be a much better method for caching valid
...
devices based on /proc/devices
+ The dev_mgr structure now has a 256 element char array that is
initially all 0s
+ When a match is found, the array element corresponding to the major
number of the match is set to a non-zero value
+ to check for a match, all one has to do is check that the array
element at the major number in question is non-zero.
o I'm wondering if we should do this with bitwise operators instead? Does
anyone expect the major numbers to grow larger than 8-bits?
