Subject: [PATCH v4 3/3] twist: Add option for selecting twist options for syzkaller's testing
Date: Tue, 21 Apr 2020 22:19:51 +0900	[thread overview]
Message-ID: <20200421131951.4948-3-penguin-kernel@I-love.SAKURA.ne.jp> (raw)
In-Reply-To: <20200421131951.4948-1-penguin-kernel@I-love.SAKURA.ne.jp>

When a kernel developer adds a kernel config option, they will not go
and update configs on all external testing systems. This problem is also
common for "enable all boot tests that can run on this kernel", or
"configure a 'standard' debug build". Currently doing these things
require all of expertise, sacred knowledge, checking all configs
one-by-one as well as checking every new kernel patch and that needs to
be done by everybody doing any kernel testing.

In order to reduce the burden of maintaining kernel config options, this
patch introduces a kernel config option which will select twist options
when building kernels for syzkaller's testing.
