Wong" To: djwong@kernel.org, zlang@redhat.com Cc: linux-xfs@vger.kernel.org, fstests@vger.kernel.org, guan@eryu.me Message-ID: <167657884566.3481377.2303088177888217916.stgit@magnolia> In-Reply-To: <167657884480.3481377.14824439551809919632.stgit@magnolia> References: <167657884480.3481377.14824439551809919632.stgit@magnolia> User-Agent: StGit/0.19 MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: fstests@vger.kernel.org From: Darrick J. Wong The parent pointers feature isn't supported on tiny 20MB filesystems because the larger directory transactions result in larger minimum log sizes, particularly with nrext64 enabled: ** mkfs failed with extra mkfs options added to " -m rmapbt=0, -i nrext64=1, -n parent=1," by test 306 ** ** attempting to mkfs using only test 306 options: -d size=20m -n size=64k ** max log size 5108 smaller than min log size 5310, filesystem is too small We don't support 20M filesystems anymore, so bump the filesystem size up to 100M and skip this test if we can't actually format the filesystem. Convert the open-coded punch-alternating logic into a call to that program to reduce execve overhead, which more than makes up having to write 5x as much data to fragment the free space.
