We used to require register_filesystem() before any mounts
(including the internal ones) could be done. For userland mounts
it's obviously right - how else could fs type name -> file_system_type
lookup be done? For internal ones, it used to be really needed for
a while, but after some

When testing ChromeOS with a 3.12 kernel from git, I encountered a
regression introduced between 3.11 to 3.12: at boot time, the kernel
failed to find any partitions on the USB disk I booted from, which uses
a GPT partition table with 12 partitions. This prevented the system
from booting.

A common way is for there to be a bitstream stored in flash which
presents an interface to download the data. I think some FPGAs with
hard bus

Some setuid binaries will allow reading of files which have read
permission by the real user id. This is problematic with files which
use %pK because the file access permission is checked at open() time,
but the kptr_restrict setting is checked at read() time. If a setuid
binary opens a %pK file
