Subject: [PATCH v3 0/5] KVM: MMU: unify and cleanup the code of walking pte list
Date: Tue, 05 Feb 2013 16:52:35 +0800 [thread overview]
Message-ID: <5110C853.4080705@linux.vnet.ibm.com> (raw)
Current code has two ways to walk pte_list, the one is pte_list_walk and
the another way is rmap_get_first and rmap_get_next, they have the same logic.
This patchset tries to unify the code and also make the code more tidy.
Patch 1: KVM: MMU: introduce mmu_spte_establish, which tries to eliminates
the different between walking parent pte list and rmap, prepare for the
later patch.
Patch 2: KVM: MMU: clarify the logic in kvm_set_pte_rmapp, which prepares for
the next patch, no logic changed.
Patch 3: KVM: MMU: unify the code of walking pte list, unify the walking code.
Patch 4: KVM: MMU: fix spte assertion, fix a minor bug and remove the duplicate
code.
Patch 5: KVM: MMU: fast drop all spte on the pte_list, optimize for dropping
all sptes on rmap and remove all the "goto restart" pattern introduced by
the Patch 3.
Marcelo, Gleb, please apply them after applying the patchset of
[PATCH v3 0/3] KVM: MMU: simple cleanups.
Changelog:
v3:
- address Gleb's comments, remove the remained "goto restart" in

Thanks!
