-Subject: [PATCH] x86/xen: Tolerate nested XEN_LAZY_MMU entering/leaving
-From: Juergen Gross <jgross@suse.com>
-Date: Fri, 08 May 2026 16:39:33 +0200
-Message-Id: <20260508143933.493013-1-jgross@suse.com>
-MIME-Version: 1.0
-Content-Type: text/plain; charset="utf-8"
-Content-Transfer-Encoding: 7bit
-
-With the support of nested lazy mmu sections it can happen that
-arch_enter_lazy_mmu_mode() is being called twice without a call of
-arch_leave_lazy_mmu_mode() in between, as the lazy_mmu_*() helpers
-are not disabling preemption when checking for nested lazy mmu
-sections.
-
-This is a problem when running as a Xen PV guest, as
-xen_enter_lazy_mmu() and xen_leave_lazy_mmu() don't tolerate this
-case.
-
-Fix that in xen_enter_lazy_mmu() and xen_leave_lazy_mmu() in order
-not to hurt all other lazy mmu mode users.
-
-Fixes: 291b3abed657 ("x86/xen: use lazy_mmu_state when context-switching")
-Signed-off-by: Juergen Gross <jgross@suse.com>
