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