[PATCH -next 0/2] md: fix two regressions related to export_rdev()

Posted by Yu Kuai 2 years, 5 months ago

From: Yu Kuai <yukuai3@huawei.com>

Those problems are found by a new mdadm test(see details in commit message)
in my VM, it's not 100% reproducible but run this test in a loop, I can
always reporduce them within 10 min.

Yu Kuai (2):
  md: don't dereference mddev after export_rdev()
  md: fix warning for holder mismatch from export_rdev()
