# F := (O, K) is 'valid' iff there is a Kconfig file (for some |
|
# arch) which contains K. |
|
# |
|
# Notice that this definition entails an 'asymmetry' between |
|
# the case 'O = ""' and the case 'O = "not"'. E.g., F may be |
|
# _invalid_ if: |
|
# |
|
# [case 'O = ""'] |
|
# 1) no arch provides support for F, |
|
# 2) K does not exist (e.g., it was renamed/mis-typed); |
|
# |
|
# [case 'O = "not"'] |
|
# 3) all archs provide support for F, |
|
# 4) as in (2). |
|
# |
|
# The rationale for adopting this definition (and, thus, for |
|
# keeping the asymmetry) is: |
|
# |
|
# We want to be able to 'detect' (2) (or (4)). |
|
# |
|
# (1) and (3) may further warn the developers about the fact |
|
# that K can be removed. |
