+
+In preparation for relaxing the first delay, this patch adds a retry
+attempt in case /sbin/init is not found. Before retrying, the code
+will wait for all device init to complete.
+
+While this patch by itself doesn't gain boot time yet (it needs follow on
+patches), the alternative already is to panic()...

+Subject: [PATCH] fastboot: remove "wait for all devices before mounting root" delay
+
+In the non-initrd case, we wait for all devices to finish their
+probing before we try to mount the rootfs.
+In practice, this means that we end up waiting 2 extra seconds for
+the PS/2 mouse probing even though the root holding device has been
+ready since a long time.
+
+The previous two patches in this series made the RAID autodetect code
+do it's own "wait for probing to be done" code, and added
+"wait and retry" functionality in case the root device isn't actually
+available.
+
+These two changes should make it safe to remove the delay itself,
+and this patch does this. On my test laptop, this reduces the boot time
+by 2 seconds (kernel time goes from 3.9 to 1.9 seconds).

+Subject: [PATCH] fastboot: remove duplicate unpack_to_rootfs()
+
+we check if initrd is initramfs first and then do real unpack. The
+check isn't required, we can directly do unpack. If initrd isn't
+initramfs, we can remove garbage. In my laptop, this saves 0.1s boot
+time. This penalizes non-initramfs case, but now initramfs is mostly
+widely used.

++ * This file implements a simple replacement for the buffer manager use
++ * of the heavyweight hardware lock.
++ * The lock is a read-write lock. Taking it in read mode is fast, and
++ * intended for in-kernel use only.
++ * Taking it in write mode is slow.
++ *
++ * The write mode is used only when there is a need to block all
++ * user-space processes from allocating a
++ * new memory area.
++ * Typical use in write mode is X server VT switching, and it's allowed
++ * to leave kernel space with the write lock held. If a user-space process
++ * dies while having the write-lock, it will be released during the file
++ * descriptor release.
++ *
++ * The read lock is typically placed at the start of an IOCTL- or
++ * user-space callable function that may end up allocating a memory area.
++ * This includes setstatus, super-ioctls and no_pfn; the latter may move
++ * unmappable regions to mappable. It's a bug to leave kernel space with the
++ * read lock held.
++ *
++ * Both read- and write lock taking is interruptible for low signal-delivery
++ * latency. The locking functions will return -EAGAIN if interrupted by a
++ * signal.
++ *
++ * Locking order: The lock should be taken BEFORE any kernel mutexes
++ * or spinlocks.
