20: # Generates kdump_subr.c
21: # mkioctls is a special-purpose script, and works fine as it is
22: # now, so it remains independent. The idea behind how it generates
23: # its list was heavily borrowed here.
24: #
25: # Some functions here are automatically generated. This can mean
26: # the user will see unusual kdump output or errors while building
27: # if the underlying .h files are changed significantly.
28: #
29: # Key:
30: # AUTO: Completely auto-generated with either the "or" or the "switch"
31: # method.
32: # AUTO - Special: Generated automatically, but with some extra commands
33: # that the auto_*_type() functions are inappropriate for.
34: # MANUAL: Manually entered and must therefore be manually updated.
