Commit 246cf9c26b ("kbuild: Warn on selecting symbols with unmet
direct dependencies") forcibly promoted ->dir_dep.tri to yes from mod.
So, the unmet direct dependencies of tristate symbols are not reported.
[Test Case]
config MODULES
def_bool y
option modules
config A
def_bool y
select B
config B
tristate "B"
depends on m
This causes unmet dependency because 'B' is forced 'y' ignoring
'depends on m'. This should be warned.
On the other hand, the following case ('B' is bool) should not be
warned, so 'depends on m' for bool symbols should be naturally treated
as 'depends on y'.
[Test Case2 (not unmet dependency)]
config MODULES
def_bool y
option modules
config A
def_bool y
select B
config B
bool "B"
depends on m

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
