[PATCH v2 0/4] KVM: x86/mmu: small locking cleanups

[Paolo Bonzini]

Remove "bool shared" argument from functions and iterators that need
not know if the lock is taken for read or write.  This is common because
protection is achieved via RCU and tdp_mmu_pages_lock or because the
argument is only used for assertions that can be written by hand.

Also always take tdp_mmu_pages_lock even if mmu_lock is currently taken
for write.

Paolo Bonzini (4):
  KVM: x86/mmu: remove unnecessary "bool shared" argument from functions

  KVM: x86/mmu: always take tdp_mmu_pages_lock
  KVM: x86/mmu: fix comment about mmu_unsync_pages_lock
