If we reflink a file with N blocks to another file one block at a time,
does the destination file end up with the same number of extents as the
source file? In other words, does the filesystem succeed at combining
adjacent mappings into a maximal extents?

Overlayfs should only filter out xattr starting with
"trusted.overlay.", not "trusted.overlay".
Setting xattrs like "trusted.overlay.xxx" is not allowed.
Setting xattrs like "trusted.overlayxxx" is allowed.
v4.8-rc1 introduced a regression that we can't set xattrs
like "trusted.overlayxxx". Kernel commit below fixed it
in v4.8:
fe2b75952347 ovl: Fix OVL_XATTR_PREFIX
This case tests both get/set of these 2 kinds of xattrs.
Pattern "trusted.overlay.xxx" should fail, however the
errno returned by set/get varies among kernel versions.
Pattern "trusted.overlayxxx" shold always work.

local warn4="WARNING:.*fs/iomap\.c:.*iomap_dio_rw.*"
The second warn4 will override the first one. So change the second

1) xfs/133 and xfs/134 work abnornamlly on RHEL6.8GA and RHEL6.9Beta
because xfs_db fails to set negative i_size and reports "usage:
write fieldname value". The special argument "--" is only used to
end option-scanning in getopt(). So we can run two xfs_db commands
to set negative i_size regardless of the special argument "--" is
needed or not. getopt() has been produced by 'commit c9f5e3db22098
("xfs_db: Allow writes of corrupted data")'.
2) xfs/134 passes unexpectedly on RHEL6.8GA due to EINVAL, so we use
touch command to create 512-aligned test file.

Test that if we have a file with a hole, do a mix of direct IO and
buffered writes to it and truncate the file to a size that lies in
the middle of the hole, after unmounting and mounting again the
filesystem, the file has a correct size and no data loss happened.
This test is motivated by a bug found in btrfs when used with the
no-holes feature (i.e. MKFS_OPTIONS="-O no-holes") which is fixed by
the following patch for the linux kernel:
