28# Generates kdump_subr.c
29# mkioctls is a special-purpose script, and works fine as it is
30# now, so it remains independent. The idea behind how it generates
31# its list was heavily borrowed here.
32#
33# Some functions here are automatically generated. This can mean
34# the user will see unusual kdump output or errors while building
35# if the underlying .h files are changed significantly.
36#
37# Key:
38# AUTO: Completely auto-generated with either the "or" or the "switch"
39# method.
40# AUTO - Special: Generated automatically, but with some extra commands
41# that the auto_*_type() functions are inappropriate for.
42# MANUAL: Manually entered and must therefore be manually updated.
