Subject: Re: [PATCH v3 0/7] Lazy flush for the auth session

Hi Jarkko,

After applied this patchset, the boot time become 8.9 secondes, it's
more reasonable.

But this patchset can't be clean applied to upstream 6.11 kernel.
looks like file tpm2-sessions.c is changed in your code base.

Tested-by: Pengyu Ma <mapengyu@...il.com>

Thanks,
Pengyu
