Nitin A Kamble - July 12, 2011, 7:02 p.m.
From: Nitin A Kamble <nitin.a.kamble@intel.com>

the 2.6.38 kernel has dropped v4lv1 support. and udev-168 fails to
compile because of that. So add a newer 172 version of udev to work with
2.6.38 kernel.

Meta-oe has had 172 since yesterday :) The main difference between the oe-core and meta-oe version is that the meta-oe version has removed a lot of udev rules that weren't needed and made booting slow. Where udev trigger used to take >8 seconds I can now boot X in less than a second on a cortex A9.

Koen

Great, then we can take meta-oe version of 172 into oe-core.
