Btrfs in-band de-duplication test case for in-memory backend.
v5:
Due to kernel ioctl change, add FORCE flag for "dedupe enable" ioctl call.
v4:
Due to kernel patchset re-organization, remove on-disk backend test cases
v3:
Add new test cases for on-disk backend with metadata balance
v2:
Add new test cases for on-disk backend with full balance
Qu Wenruo (4):
fstests: rename _require_btrfs to _require_btrfs_subcommand
fstests: btrfs: Add basic test for btrfs in-band de-duplication
fstests: btrfs: Add testcase for btrfs dedupe and metadata balance
race test
fstests: btrfs: Test inband dedupe with data balance.

Rename _require_btrfs() to _require_btrfs_subcommand() to avoid
confusion, as all other _require_btrfs_* has a quite clear suffix, like
_require_btrfs_mkfs_feature() or _require_btrfs_fs_feature().

Add basic test for btrfs in-band de-duplication(inmemory backend), including:
1) Enable
3) Dedup rate
4) File correctness
5) Disable

Btrfs balance with inband dedupe enable/disable will expose a lot of
hidden dedupe bug:
1) Enable/disable race bug
2) Btrfs dedupe tree balance corrupted delayed_ref
3) Btrfs disable and balance will cause balance BUG_ON

Btrfs balance will reloate date extent, but its hash is removed too late
at run_delayed_ref() time, which will cause extent ref increased
during balance, cause either find_data_references() gives WARN_ON()
or even run_delayed_refs() fails and cause transaction abort.
Add such concurrency test for inband dedupe and data balance.

Hi Qu, you might want to CC fstests@vger.kernel.org on these patches.
Thanks,

Not yet.
This is for btrfs internal review.

Until ioctl interface and user-tools command are settled, such test

Thanks,
Qu
