Subject: [PATCH lib/bitmap 2/9] lib: test_bitmap: add tests to trigger ERANGE case.
Date: Wed, 3 Mar 2021 15:56:09 -0800 [thread overview]
Message-ID: <20210303235616.22093-2-paulmck@kernel.org> (raw)
In-Reply-To: <20210303235526.GA21868@paulmck-ThinkPad-P72>
From: Paul Gortmaker <paul.gortmaker@windriver.com>
Add tests that specify a valid range, but one that is outside the
width of the bitmap for which it is to be applied to. These should
trigger an -ERANGE response from the code.
