1#
2#        On the handling of kernel options
3#
4# All kernel options should be listed in NOTES, with suitable
5# descriptions.  Negative options (options that make some code not
6# compile) should be commented out; LINT (generated from NOTES) should
7# compile as much code as possible.  Try to structure option-using
8# code so that a single option only switch code on, or only switch
9# code off, to make it possible to have a full compile-test.  If
10# necessary, you can check for COMPILING_LINT to get maximum code
11# coverage.
12#
13# All new options shall also be listed in either "conf/options" or
14# "conf/options.<machine>".  Options that affect a single source-file
15# <xxx>.[c|s] should be directed into "opt_<xxx>.h", while options
16# that affect multiple files should either go in "opt_global.h" if
17# this is a kernel-wide option (used just about everywhere), or in
18# "opt_<option-name-in-lower-case>.h" if it affects only some files.
19# Note that the effect of listing only an option without a
20# header-file-name in conf/options (and cousins) is that the last
21# convention is followed.
22#
23# This handling scheme is not yet fully implemented.
24#
25#
26# Format of this file:
27# Option name	filename
28#
29# If filename is missing, the default is
30# opt_<name-of-option-in-lower-case>.h
