For fsck tests, we check the subpage warnings for each type 1 test, but
such type 1 tests are mostly read-only tests, and one of the test will
trigger new subpage related warnings (fsck/018).
For subpage related warnings, what we really care are write operations,
including mkfs, btrfs-convert and repair, not those read-only tests.
So skip the subpage warning check for fsck type 1 tests to prevent false
alert of later more strict subpage warnings.

Introduce a new function, check_test_results(), for
misc/fsck/convert/mkfs test cases.
This function is currently to catch warning message for subpage support,
but can be later expanded for other usages.

As the TEST_TOP is often only a base path, the slash gets doubled. This
is not a problem as the slashes are in the middle of the path and cannot
be confused with the initial "//" that gets interpreted as a network
path. Update all the test drivers.

Make the TOP variable more configurable, allow to set it to any path
where to find binaries when the testsuite is exported, or fallback to
system binaries.
There's now more code duplication, the logic is now more complex so it's
left open coded for clarity. Further cleanups are possible.

Use TEST_TOP as base for tests to reference any files, this will be used
for git and external testsuite.
INTERNAL_BIN is needed for referencing binaries that could reside in
different paths in git vs external testsuite.

For example, $TEST_DIR is common used in severial tests, and have
duplicated code for initialize.
These duplicated code not only benifits harddisk vendor, but have
inconsistent details, as:
convert-tests.sh: lack of mkdir
fsck-tests/012-leaf-corruption/test.sh: unnecessary mkdir
fsck-tests/013-extent-tree-rebuild/test.sh: unnecessary init
misc-tests/XXX ...
And severial error message:
_fail "unable to create mount point on $TEST_MNT"
_fail "failed to create mount point"
...
This patch move initizlizaton of $TEST_DIR to common init_env(),
to avoid above problem, and init_env() can be used to add more
things in future.

To run a given test set the variable TEST like
$ make test TEST=002-bad-transid
$ make test TEST=002-*
and only tests matching the value will be run. The pattern is glob and
pased to 'find -name'.
The convert tests do not follow the fsck and misc layout and are skipped
if TEST is set.

Change the old btrfsck test infrastructure (btrfs-image dump or xz raw
dump) to the new test infrastructure.
1) Test case layout
The new infrastructure is dir based, each dir is one test type, and can
contain multiple images/scripts for different corner cases.
So layout will be the following:
btrfs-progs
|-tests
|-fsck-tests
|-001-SOME-CORRUPT-TYPE
|-IMAGE-FOR-CASE1
|-IMAGE-FOR-CASE2
2) Test case image types
Only 2 types for test case images.
a) btrfs-image dump
This one is the simplest case, one only needs to add the image to
corresponding dir.
b) custom script
This one is for all the resting cases which can't fit btrfs-image,
like csum error or script can generate the image (this reduces the
size obviously and good for review)
The old binary dump also belongs to this type, so need to add script
to extract them.

This change adds code to detect and fix the issue introduced in the kernel
release 3.17, where creation of read-only snapshots lead to a corrupted
filesystem if they were created at a moment when the source subvolume/snapshot
had orphan items. The issue was that the on-disk root items became incorrect,
referring to the pre orphan cleanup root node instead of the post orphan
cleanup root node.
A test filesystem can be generated with the test case recently submitted for
xfstests/fstests, which is essencially the following (bash script):
workout()
{
ops=$1
procs=$2
num_snapshots=$3
_scratch_mkfs >> $seqres.full 2>&1
_scratch_mount
snapshot_cmd="$BTRFS_UTIL_PROG subvolume snapshot -r $SCRATCH_MNT"
snapshot_cmd="$snapshot_cmd $SCRATCH_MNT/snap_\`date +'%H_%M_%S_%N'\`"
run_check $FSSTRESS_PROG -p $procs \
-x "$snapshot_cmd" -X $num_snapshots -d $SCRATCH_MNT -n $ops
}
ops=10000
procs=4
snapshots=500
workout $ops $procs $snapshots

We need to start adding some sanity tests to btrfs-progs to make sure we aren't
breaking things with our patches. The most important of these tools is btrfsck.
This patch gets things started by adding a basic btrfsck test that makes sure we
can fix a corruption problem we know we can fix. Thanks,
