From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sandeep Patil Date: Sat, 18 May 2019 17:38:07 -0700 Subject: [LTP] [PATCH 4/5] syscalls/bdflush01: delete bdflush test In-Reply-To: <20190519003808.47425-1-sspatil@android.com> References: <20190519003808.47425-1-sspatil@android.com> Message-ID: <20190519003808.47425-5-sspatil@android.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ltp@lists.linux.it The manual says the system call is deprecated since Linux 2.6 and does nothing. So, remove the test.
