Series [1/6,v3] KVM: x86: Change names of some of the kvm_x86_ops functions to make them more semantical and readable | expand

Commit Message

Krish Sadhukhan July 28, 2020, 12:10 a.m. UTC 
The names of some of the svm_x86_ops functions do not have a corresponding
'svm_' prefix. Generate the names using a macro so that the names are
conformant. Fixing the naming will help in better readability and
maintenance of the code.

I'd probably prefer to split this into two patches, one to rename all the
functions and then the second to introduce the autofill macros.  Ditto for
VMX.
