[OE-core] [PATCH 1/1] systemd: Upgrade to 199

Thu Mar 28 07:48:29 UTC 2013
udevadm is now moved from /usr/bin to /bin so account for that
bash completions for udevadm should be packages with udev-utils
since thats where udevadm itself is, they were in systemd package
which is not correct location for it
Backport patches for readahead fixes on spinning disks
and to tackle error reported on missing /etc/sysctl.conf

+Subject: [PATCH 02/17] readahead: chunk on spinning media
+
+Readahead has all sorts of bad side effects depending on your
+storage media. On rotating disks, it may be degrading startup
+performance if enough requests are queued spanning linearly
+over all blocks early at boot, and mount, blkid and friends
+want to insert reads to the start of these block devices after.
+
+The end result is that on spinning disks with ext3/4 that udev
+and mounts take a very long time, and nothing really happens until
+readahead is completely finished.
+
+This has the net effect that the CPU is almost entirely idle
+for the entire period that readahead is working. We could have
+finished starting up quite a lot of services in this time if
+we were smarter at how we do readahead.
+
+This patch sorts all requests into 2 second "chunks" and sub-sorts
+each chunk by block. This adds a single cross-drive seek per "chunk"
+but has the benefit that we will have a lot of the blocks we need
+early on in the boot sequence loaded into memory faster.
+
+For a comparison of how before/after bootcharts look (ext4 on a
+mobile 5400rpm 250GB drive) please look at:
+
+ http://foo-projects.org/~sofar/blocked-tests/
+
+There are bootcharts in the "before" and "after" folders where you
+should be able to see that many low-level services finish 5-7
+seconds earlier with the patch applied (after).
