Subject: [PATCH 0/2] kho: fixes for vmalloc restoration
Date: Tue, 25 Nov 2025 13:09:15 +0200 [thread overview]
Message-ID: <20251125110917.843744-1-rppt@kernel.org> (raw)
From: "Mike Rapoport (Microsoft)" <rppt@kernel.org>
Hi,
Pratyush reported off-list that when kho_restore_vmalloc() is used to
restore a vmalloc_huge() allocation it hits VM_BUG_ON() when we reconstruct
the struct pages in kho_restore_pages().
These patches fix the issue.
Mike Rapoport (Microsoft) (2):
kho: kho_restore_vmalloc: fix initialization of pages array
kho: fix restoring of contiguous ranges of order-0 pages
