LVM2 update/Ubuntu changes

[Phillip Susi]

I've been hoping to see the LVM2 package updated in maverick for the new 
upstream snapshot merge support, allowing testing of updates with the 
possibility of reverting when things go tits up.  It seems that this has 
not been done because the last time Ubuntu merged the package from 
debian, it was such a nightmare, nobody can make heads or tails of the 
bzr history and nobody wants to touch it again.  I've been looking at it 
trying to merge it myself, and it seems that Ubuntu is carrying a number 
of quilt patches that do not apply to the new upstream sources, and have 
no documentation to help me figure out what they are supposed to do and 
if they are still needed.

Can anyone provide some description of what the following undocumented 
patches are supposed to do, and why they are required?

implicit-pointer.patch
install.patch
libdm-atomic.patch
libdm-event-static.patch
libdm-static.patch
libs-cleanup.patch
rules-subdir.patch
