03aedda156 o Added a file containing a TODO list.
Please add to/edit this file as you think of new ideas or discover bugs. The
items in it are in no particular order. They are also only ideas and hence may
never get implemented depending on whether they turn out to be good ideas or
not.

c3ceee769f o It's a bit of a hack, but the regex filter now makes sure a device path
that passed the filter is at the front of the aliases list.

c7f0b573ac o use dev_name(dev) to get the name of a device, this operation is cheap

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.

14ce9d49f1 Ok. this is the big one.... the change to the new fs interface.
Things to note:

 o Changes to the dm-*.c files have been kept as small as possible during
   the development of the new fs interface and there are a few places where
   the new code does odd things to give the original code what it wants. These
   places will gradually go away during the next few days once we are sure the
   new code is sound.
 o I've spent most of my testing time looking at the parser since thats where
   a lot of the changes are, I've not checked the actual I/O very much, but
   then that code hasn't changed at all.
 o The print operation in the target type operations is there to help in
   debugging and will go away eventually
 o There are some other printk's which will also go away once we are sure that
   things are working correctly.
 o I've tagged the old code with PRE_DMFS if you want to use that until this is
   stable.
 o There are no kernel patches for this yet (will fix after lunch... :-)
      o Makefile needs some changes
      o need to EXPORT_SYMBOL(deny_write_access); in ksyms.c

How to use the new interface ?

 mount -t dmfs dmfs /mnt/dm
 cd /mnt/dm
 mkdir fish fish/tank
 cd fish/tank
 cat ~/my.table > table
 cd ..
 ln -s tank ACTIVE

Creates a logical volume called fish and activates a table called tank, if
there is a problem doing the link, look in /mnt/dm/fish/tank/errors to see
what is wrong.

If you see any odd things happening, let me know right away as I'm sure there'll
be one or two things that slipped through my testing.
