0f29dc2f2d o split struct mapped_device into mapped_device and dm_table
o seperated loading of a table from binding a table to the device

These should allow multiple tables to be managed by dm-fs

a53d451f30 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?

83b2c0d30a o Quick and dirty *UGLY* hack of a /proc/devices cache using a linked list

o I'm working on caching the /proc/devices entries now, and should have
   that in by the end of today or early tomorrow.
 o There will be much cleanup involved with that...

9404455a07 dec use count on close. corrects a typo.
Really the use counts on these modules should be handled at a higher level,
otherwise there are races I think.
