Subject: [PATCH v1 0/2] KVM: s390: fix two newly introduced bugs
Date: Thu, 13 Feb 2025 21:07:53 +0100 [thread overview]
Message-ID: <20250213200755.196832-1-imbrenda@linux.ibm.com> (raw)
* fix race when making a page secure (hold pte lock again)
* fix issues when splitting folios (use split_huge_page_to_list_to_order())
This should fix the issues I have seen, which I think/hope are also the same
issues that David found.
