Subject: [PATCH v13 08/24] selftests/vm: fix the wrong assert in pkey_disable_set()
Date: Wed, 13 Jun 2018 17:44:59 -0700 [thread overview]
Message-ID: <1528937115-10132-9-git-send-email-linuxram@us.ibm.com> (raw)
In-Reply-To: <1528937115-10132-1-git-send-email-linuxram@us.ibm.com>
If the flag is 0, no bits will be set. Hence we cant expect
the resulting bitmap to have a higher value than what it
was earlier.
