o I'm afraid that wu and wl etc. is just too confusing.... I've changed it
...
to up_write() and down_write() etc so that you can see what kind of a lock
it is (otherwise it could be anything.. semaphore, spinlock, spinlock_bh,
spinlock_irq, br_lock, etc.)

o first sattab at custom fs. Very rough ATM.
...
Mount the dm-fs filesystem on /device-mapper (will fix later). mkdir
to create a device, inside that directory every file you create is a table
file. If there are errors <table>.err will appear automagically. Mv a table
file to ACTIVE to activeate the device. I'm not happy with mv being the
binding command, symlink would be better.

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?
