12eabe3031 o composite filter that allows us to merge filters. Think of it as &&'ing 
filters in order.

eg,

	f = composite_filter_create(2, regex_filter, persistent_filter);

  ownership of the filters passes, they will be destroyed when f's
  destroy method is called.

5f16718b19 o Filter which caches valid devices in a file. Pass in init == 1 to the 
constructor if you want it to ignore the existing cache and check every
  device again (eg, vgscan, pvscan).

291ec3b6c0 o Filter for the dev cache that takes values from config file: 
devices {

        # first match is final, eg.  /dev/ide/cdrom
		        # get's rejected due to the first pattern

					filter=["r/cdrom/",         # don't touch the music !
							"a/hd[a-d][0-9]+/",
							"a/ide/",
							"a/sd/",
							"a/md/",
							"a|loop/[0-9]+|", # accept devfs style loop back
							"r/loop/",        # and reject old style
							"a/dasd/",
							"a/dac960/",
							"a/nbd/",
							"a/ida/",
							"a/cciss/",
							"a/ubd/",
							"r/.*/"] # reject all others
}


Alasdair this is ready to roll into the tools now.

d1b28647ed o First pass at the regex code. lib/regex/matcher takes an array of regex's 
and builds a *very* efficient engine that will tell you which regex a string
  matches with only a single pass through the string.  To be used in the config
  file when specifying devices.

o Anchor's aren't supported yet (^ and $) but that won't take long.

o Also when we get some realistic config files we may want to consider adding an
  extra level of indirection to the dfa state in order to compress the table.
  It all depends on how large typical tables get.

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?
