[ Upstream commit 5384cc0d1a88c27448a6a4e65b8abe6486de8012 ]
When getting kernel version via make, the result may be polluted by other output, like directory change info. e.g.
$ export MAKEFLAGS="-w" $ make kernelversion make: Entering directory '/home/net' 6.8.0 make: Leaving directory '/home/net'
This will distort the reStructuredText output and make latter rst2man failed like:
[...] bpf-helpers.rst:20: (WARNING/2) Field list ends without a blank line; unexpected unindent. [...]
Using silent mode would help. e.g.
$ make -s --no-print-directory kernelversion 6.8.0
