[PATCH 2/4] KVM: x86/mmu: Remove function comments above clear_dirty_{gfn_range,pt_masked}()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Drop the comments above clear_dirty_gfn_range() and
clear_dirty_pt_masked(), since each is word-for-word identical to the
comment above their parent function.

Leave the comment on the parent functions since they are APIs called by
the KVM/x86 MMU.

No functional change intended.
