Oleg believes there is a fix in 2.5 for this that just needs to be ported to 2.4.
Could you please take a look at this?
Thank you!

Hi nasf,

Do you know which patch on master branch fixed this issue?

[Jian Yu]

The patch on master branch is:

commit f5491211ed7251a45e4e6916539cd2a2ab5e6038

    LU-2915 lfsck: LFSCK 1.5 technical debts (2)
    
    This patch resolves some LFSCK 1.5 technical debts, including:
    1) LFSCK does NOT hold spin_lock when call dt iteration API(s).
    2) Remove the hack of using dt_it_ops::put() method for events
       notification to low layer otable-based iteration.

As per the suggestion from Nasf, we only need add Lustre version check code into sanity-scrub test 10b on Lustre b2_4 branch to resolve the interop failure. I'll upload the patch.
