Subject: [PATCH linux-next] testing/vm/: fix application of sizeof to pointer
Date: Thu, 19 Aug 2021 20:24:30 -0700 [thread overview]
Message-ID: <20210820032430.12948-1-jing.yangyang@zte.com.cn> (raw)
From: jing yangyang <jing.yangyang@zte.com.cn>
sizeof when applied to a pointer typed expression gives the size of the
pointer.
./tools/testing/selftests/vm/split_huge_page_test.c:344:36-42: ERROR application
of sizeof to pointer
This issue was detected with the help of Coccinelle.
