Date: Thu, 26 Mar 2015 14:37:10 +0530 Message-Id: <1427360830-6209-1-git-send-email-chandan@linux.vnet.ibm.com> X-Mailer: git-send-email 2.1.0 X-TM-AS-MML: disable X-Content-Scanned: Fidelis XPS MAILER x-cbid: 15032609-0005-0000-0000-000004738ED6 Sender: linux-btrfs-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-btrfs@vger.kernel.org X-Spam-Status: No, score=-6.9 required=5.0 tests=BAYES_00, RCVD_IN_DNSWL_HI, T_RP_MATCHES_RCVD, UNPARSEABLE_RELAY autolearn=unavailable version=3.3.1 X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on mail.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP The test case passes file offsets which are aligned to 4k block size. This causes btrfs_ioctl_clone() to return with -EINVAL for larger block sizes. Fix this by computing file offsets at run time based on the block size of the underlying filesystem. Signed-off-by: Chandan Rajendra --- There are some more test cases which assume 4k as the underlying filesystem's block size. I am planning to fix them using the final solution agreed upon by the community. common/filter | 37 ++++ tests/btrfs/052 | 125 +++++++----- tests/btrfs/052.out | 546 +++++++++++++++++++++++----------------------------- 3 files changed, 358 insertions(+), 350 deletions(-) diff --git a/common/filter b/common/filter index 71ef2e2..750e165 100644 --- a/common/filter +++ b/common/filter @@ -233,6 +233,30 @@ _filter_xfs_io_unique() common_line_filter | _filter_xfs_io } +_filter_xfs_io_blocks_modified() +{ + BLOCK_SIZE=$(get_block_size $SCRATCH_MNT) + + $AWK_PROG -v block_size=$BLOCK_SIZE ' + /wrote/ { + split($2, bytes, "/") + + bytes_written = strtonum(bytes[1]) + + offset = strtonum($NF) + + block_start = offset / block_size + block_start = int(block_start) + block_end = (offset + bytes_written - 1) / block_size + block_end = int(block_end) + + printf("Blocks modified: [%d - %d]\n", block_start, block_end) + + next + } + ' +} + _filter_test_dir() { sed -e "s,$TEST_DEV,TEST_DEV,g" -e "s,$TEST_DIR,TEST_DIR,g" @@ -327,5 +351,18 @@ _filter_ro_mount() { -e "s/mount: cannot mount block device/mount: cannot mount/g" } +_filter_od() +{ + BLOCK_SIZE=$(get_block_size $SCRATCH_MNT) + $AWK_PROG -v block_size=$BLOCK_SIZE ' + /^[0-9]+/ { + offset = strtonum("0"$1);
