The mount_root() Function
Mount_root() is located in fs/super.c.
Mount_root() tries to mount the root filesystem. The identity of the root
filesystem is provided as a kernel option during boot, which in workstation
environments is typically the hard disk device and partition containing the
system's root directory. (The root partition isn't necessarily the same as
the location of the now almost-booted kernel image.)
Linux can mount root filesystems from hard disks, floppies, and over a
network NFS connection to another machine. Linux can also use a ramdisk as a
root filesystem. Mount_root() will try one or more of these sources before
giving up and causing a kernel panic.
