Hi Song,
the first patch in this series fixed the reported lock order reversal
in md_alloc. The rest sort out the error handling in that function,
starting with the patch from Luis to handle add_disk errors, which
would otherwise conflict with the first patch.
Thanks for the fixes! I have noticed the issue, but haven't got a good
solution for it. I will test and apply the set (maybe after the labor day
long weekend).
Note that I have had a hard time verifying this all works fine as the
testsuite in mdadm already keeps failing a lot for me with the baseline
kernel. Some of thos reproducibly and others randomly. Is there a
good document somehow describing what to expect from the mdadm test
suite?
Unfortunately, mdadm test needs quite some work to be really useful again.
I will work with Jes and other folks to come up with a plan for this.
Thanks again,
Song
