---- 6.3 Symbols From Another External Module
+6.3 Symbols From Another External Module
+----------------------------------------
Sometimes, an external module uses exported symbols from
- another external module. kbuild needs to have full knowledge of
+ another external module. Kbuild needs to have full knowledge of
all symbols to avoid spitting out warnings about undefined
symbols. Three solutions exist for this situation.
The top-level kbuild file would then look like::
#./Kbuild (or ./Makefile):
- obj-y := foo/ bar/
+ obj-m := foo/ bar/
And executing::
Timestamps
----------
-The kernel embeds a timestamp in two places:
+The kernel embeds timestamps in three places:
* The version string exposed by ``uname()`` and included in
``/proc/version``
* File timestamps in the embedded initramfs
-By default the timestamp is the current time. This must be overridden
-using the `KBUILD_BUILD_TIMESTAMP`_ variable. If you are building
-from a git commit, you could use its commit date.
+* If enabled via ``CONFIG_IKHEADERS``, file timestamps of kernel
+ headers embedded in the kernel or respective module,
+ exposed via ``/sys/kernel/kheaders.tar.xz``
+
+By default the timestamp is the current time and in the case of
+``kheaders`` the various files' modification times. This must
+be overridden using the `KBUILD_BUILD_TIMESTAMP`_ variable.
+If you are building from a git commit, you could use its commit date.
The kernel does *not* use the ``__DATE__`` and ``__TIME__`` macros,
and enables warnings if they are used. If you incorporate external

recvfrom(2) can provide. For example package priority and timestamp. The
