[lvm-devel][PATCH 1/4] Udev integration: add LVM fields support for dmsetup

[Dave Wysochanski]

A couple minor cleanup comments for this patch set:
1. Warnings when compiling these patches. 
ioctl/libdm-iface.c:867: warning: no previous prototype for ‘dm_cookie_supported’
dmsetup.c:332: warning: assignment discards qualifiers from pointer target type

2. whitespace / tabs - set to 8 spaces / tab?
Areas I noticed were dm_cookie_supported() definitions and other
indents.
