[PATCH v4 01/37] KVM: x86: Rename 'enable_direct_tlbflush' to 'enable_l2_tlb_flush'

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

 



To make terminology between Hyper-V-on-KVM and KVM-on-Hyper-V consistent,
rename 'enable_direct_tlbflush' to 'enable_l2_tlb_flush'. The change
eliminates the use of confusing 'direct' and adds the missing underscore.

No functional change.
