[PATCH v5 0/4] Btrfs in-band de-duplication test cases

[Qu Wenruo]

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.

[PATCH v5 1/4] fstests: rename _require_btrfs to _require_btrfs_subcommand

[Qu Wenruo]

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().

[PATCH v5 3/4] fstests: btrfs: Add testcase for btrfs dedupe and metadata balance race test

[Qu Wenruo]

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

[PATCH v5 4/4] fstests: btrfs: Test inband dedupe with data balance.

[Qu Wenruo]

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.

Re: [PATCH v5 0/4] Btrfs in-band de-duplication test cases

[Qu Wenruo]

Not yet.

This is for btrfs internal review.
Since I'm still not sure if current ioctl is settled.

Until ioctl interface and user-tools command are settled, such test 
cases won't be sent to fstests.

Thanks,
Qu
