# WARNING/NOTE: whenever you want to add an option here you need to either
|
|
# * mark it as an optional one with `option`,
|
|
# * or make sure it works for all the versions in nixpkgs,
|
|
# * or check for which kernel versions it will work (using kernel
|
|
# changelog, google or whatever) and mark it with `whenOlder` or
|
|
# `whenAtLeast`.
|
|
# Then do test your change by building all the kernels (or at least
|
|
# their configs) in Nixpkgs or else you will guarantee lots and lots
|
|
# of pain to users trying to switch to an older kernel because of some
