Subject: What's in fastboot.git for 2.6.28
Date: Sat, 20 Sep 2008 11:00:36 -0700	[thread overview]
Message-ID: <20080920110036.302261c7@infradead.org> (raw)

The fastboot.git tree has a set of patches (all posted and reviewed on lkml before)
that speed up the kernel boot process of the kernel.

There's 3 major pieces of this
1) The creation of an asynchronous initcall level (6a) that runs asynchronous from
   the regular driver init, and is for non-boot critical initcalls only
2) A rework of the non-initrd boot code to try mounting /, and if that fails,
   only THEN wait for all the various driver probings to finish (and then retry)
3) A tool "bootgraph.pl" that outputs a SVG graphic of where the kernel boot spends
   its time 


The following changes since commit 9824b8f11373b0df806c135a342da9319ef1d893:
