Aditionally, a special "ranged" argument is added to the require_xfs_io_command which checks for the presence of fiemap range support. Signed-off-by: Nikolay Borisov --- V5: * Drop changes to existing generic punch hole tests since the new fiemap implementation don't require them * Merge the common/rc change with this patch * Added Data + Hole + Data and Hole + Data tests as per Eryu's request * Adjusted output of some tests which fall in a hole, since holes are truncated to passed range * Simplified the logic to check for fiemap range support (Eryu) V4: * Added test description * Added new test for past-eof behavior * Removed supported_generic_fs line * Switched to using the "ranged" param require * Revert v3 changes V3: * Adjusted tests for '-r' fiemap param * Tests for invalid -r combination V2: No change V1: No change common/rc | 7 +++ tests/xfs/900 | 101 +++++++++++++++++++++++++++++++++++++++++++ tests/xfs/900.out | 125 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 233 insertions(+) create mode 100755 tests/xfs/900 create mode 100644 tests/xfs/900.out diff --git a/common/rc b/common/rc index e2a8229..d0dd32d 100644 --- a/common/rc +++ b/common/rc @@ -2053,6 +2053,13 @@ _require_xfs_io_command() -c "$command 4k 8k" $testfile 2>&1` ;; "fiemap") + # If 'ranged' is passed as argument then we check to see if fiemap supports + # ranged query params + if echo "$param" | grep -q "ranged"; then + param=$(echo "$param" | sed "s/ranged//") + $XFS_IO_PROG -c "help fiemap" | grep -q "\[offset \[len\]\]" + [ $? -eq 0 ] || _notrun "xfs_io $command ranged support is missing" + fi testio=`$XFS_IO_PROG -F -f -c "pwrite 0 20k" -c "fsync" \ -c "fiemap -v $param" $testfile 2>&1` param_checked=1 diff --git a/tests/xfs/900 b/tests/xfs/900 new file mode 100755 index 0000000..07f4f40 --- /dev/null +++ b/tests/xfs/900 @@ -0,0 +1,101 @@ +#! /bin/bash +# FS QA Test No. 900 + +# Test for the new ranged query functionality in xfs_io's fiemap command. +# This tests various combinations of hole + data layout being printed. +# Also the test used 16k holes to be compatible with 16k block filesystems + +#----------------------------------------------------------------------- +# Copyright (c) 2017 SUSE Linux Products GmbH.
