Comment 7 for bug 1185394

Also a braindump it gets late. Tried to figure out what changed between the udev-175 udevd and the new one. Taking away the whitespace changes. Most things are log function renames. Thought there is a hunk missing that would copy dev entries but that might have been old support code for tmpfs /dev.
There is also a related change missing from us which was handling events with timeout as urgently as dm cookie ones. And it looks a bit as the number of workers got reduced from min 128 to 8 + <nr cpus> * 2.
