Subject: [PATCH v2 0/1] s390/mm: Fix handling of _PAGE_UNUSED pte bit
Date: Mon, 15 Jun 2026 11:17:40 +0200	[thread overview]
Message-ID: <20260615091741.76724-1-imbrenda@linux.ibm.com> (raw)

Fix handling of _PAGE_UNUSED pte bit. The bit was lingering around
longer than it should have, causing issues.

This patch replaces "s390/pgtable: Unconditionally clear _PAGE_UNUSED"
which also solved the issue in practice, but in the wrong way.

v1->v2:
* Completely different approach, entirely new patch
