Subject: [PATCH v4 0/3] Fix crashes and warnings in ext4 unit test

v3->v4:
-fix that sbi->s_dirtyclusters_counter is used before
initialization.

v2->v3:
-fix warning that sb->s_umount is still held when unit test finishs
-fix warning that sbi->s_freeclusters_counter is used before
initialization.

v1->v2:
-properly handle error from sget()

Previously, the new mballoc unit tests are only tested by running
"./tools/testing/kunit/kunit.py run ..." in which case only rare configs
are enabled.
This series fixes issues when more debug configs are enabled. Fixes are
tested with and without kunit_tool [1].

[1] https://docs.kernel.org/dev-tools/kunit/run_manual.html

Kemeng Shi (3):
  ext4: alloc test super block from sget
  ext4: hold group lock in ext4 kunit test
  ext4: initialize sbi->s_freeclusters_counter and
    sbi->s_dirtyclusters_counter before use in kunit test
