Hi Helen,

Thanks for looking into the issue!

Nit: it's better to directly Cc original syzbot emails
(syzbot+901d48e0b95aed4a2548@xxxxxxxxxxxxxxxxxxxxxxxxx in this case)
when sending commands to it, otherwise it may not recognize the bug.

#syz fix: xfrm: fix refcount leak in xfrm_migrate_policy_find

Which is clear by the commit message and I also reverted it on upstream/master and validated it reproduces. So I'm marking it as fixed:
