4f3ccdd518 btrfs-progs: convert-test: Check if the ext2_save/image is read only
Old convert codes uses both 0400 permission and INODE_READONLY flag to
make the converted ext2 image readonly.

While new convert treat the inode just as normal inode, with no special
inode flag and uses 0600 permission.
This makes user able to modify converted image unintentionally and make
rollback fails.

This test case will test the regression.

2e58edbdf4 btrfs-progs: convert-test: Add test case for discontinuous hole extent
For ext* fs containing a large hole(larger than 128M), btrfs-convert
will only insert one 128M hole extent and skip the remaining.

This leads to discontinuous file extents.

Add test case for it, and since it's a pinpoint regression test case, no
combination of convert options nor checksum verification.

82aaf603e0 btrfs-progs: tests: 001-simple-unmounted: fix test failure due to bashism
The usage of 'source' is a bashism, and '.' should be used instead.  This
is causing fuzz-tests/001-simple-unmounted to fail in systems where
/bin/sh isn't bash:

    [TEST/fuzz]   001-simple-unmounted
./test.sh: 5: ./test.sh: source: not found

./test.sh: 8: ./test.sh: check_prereq: not found
./test.sh: 18: ./test.sh: check_all_images: not found

Since most (all?) tests actually use /bin/bash, change this test to use
bash too.

dc4bbc37a1 btrfs-progs: convert-tests: Add test case for backup superblock migration
New convert introduced simpler chunk/extent allocation algorithm, at the
cost of complex backup superblock migration codes.

Use specially built ext2 images to test if btrfs-convert can convert and
rollback images without problem.

All these special ext2 image have blocks/holes across 2nd btrfs backup
superblock.

The naming of test image is like the following:
	|<------superblock migration range----->|
	64M					64M + 64K
|-Data--|-Data--|/Hole//|-Data--|/Hole//|-Data--|--Data--| = drdhdhdrd

These test cases should check all typical layouts and make sure new
convert works.

New convert framework uses new and simpler chunk layout, while the cost
is the more complex superblock range migration logical, compared to old

Enhance the convert test script to create file which will takes up 2nd

as expected.

f2c844f65f btrfs-progs: mkfs: do not truncate the image when --rootdir is set
With the rootdir option we try to guess the final size of the image and
fill it with zeros, preceded by truncation. After patch

"Btrfs-progs: Do not force mixed block group creation unless '-M' option
 is specified"

the misc test 002 will fail, because of the non-mixed mode. I think we
should not touch the image size (no change for block devices) and try to
fit into whatever is provided by user.

Add a way to wrap commands executed by the tests. This means the
common wrappers: run_check, run_check_stdout and run_mayfail , with the
exception of the use root_helper.

The contents of the shell variable INSTRUMENT are prepended to the
command, without quotes. Use with care.

Example: this has been tested with valgrind, the output goes to the
RESULTS file.

 $ INSTRUMENT=valgrind make test-misc

Any use of root_helper/SUDO_HELPER will skip the instrumentation.

To check is btrfs-convert create bad filesystem with
leaf across stripes.

It is happened in progs version <=v4.1.2, and fixed by patch titled:
btrfs: convert: Avoid allocating metadata extent crossing stripe boundary
which was merged in v4.2.

Notice thar this testcase can not report error in old version of
btrfs-progs, because "btrfs check" can't check this type of error
in those version, but we have another testcase in fsck-tests, to
check is "btrfs check" support this check.

So, the above 2 testcase together can check leaf-crossing-stripes
