2012-06-05readahead: Add tool to analyze the contents of the pack file. v3.Auke Kok
This patch adds code to compile 'systemd-readahead-analyze' and install it into $bindir. Use this program to parse the contents of the readahead pack file, or an arbitrary pack file and display which files are listed in it, and how much of the files are requested to be readahead. This code is not new - it's partially taken from sreadahead (formerly maintained by Arjan van der Ven and me, and was originally written by me), and adapted with the right bits to parse the systemd readahead pack files, which are slightly different in format. v2 adds a common READAHEAD_PACK_FILE_VERSION used in all the code to provide a quick way to assure all these programs are always synchronized. v3 fixes the integer math.

2012-05-04readahead: store inode numbers in pack fileLennart Poettering
If the inode nr for each file is available in the pack file we can easily detect replaced files (like they result from package upgrades) which we can then skip to readahead.

2012-05-04readhead: temporarily lower the kernel's read_ahead_kb setting while collectingLennart Poettering
While collecting readahead data we want to know exactly what userspace accesses unblurred by the kernel's read_ahead_kb. Hence lower this during collection, and raise it afterwards. This is mostly based on ideas and code by Auke Kok.

2012-04-12relicense to LGPLv2.1 (with exceptions)Lennart Poettering
We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.
