Message-ID: <0C09AFA07DD0434D9E2A0C6AEB0483103B97F2D1@shsmsx102.ccr.corp.intel.com> (raw)
In-Reply-To: <20171003212834.25740-3-lersek@redhat.com>

Minor comment:

How about also to fix the comment for Attributes parameter of SetVariableCheckHandlerMor() like below?

  @param[in]  Attributes         Attributes bitmask to set for the variable.


Thanks,
Star

Subject: [PATCH 2/6] MdeModulePkg/Variable/RuntimeDxe: move MOR func. declarations to header

The MorLockInit() and SetVariableCheckHandlerMor() functions have separate implementations for VariableRuntimeDxe (= unprivileged, unified DXE_RUNTIME driver) and VariableSmm (= privileged, DXE_SMM back-end of the split variable driver).

Move their declarations from "Variable.c" to "PrivilegePolymorphic.h", so that the compiler enforce that the declarations and the definitions match.
(All C source files with the call sites and the function definitions already include "PrivilegePolymorphic.h" via "Variable.h".)

At the same time:

- replace two typos in the MorLockInit() description:
  - replace "EFI_SUCEESS" with "EFI_SUCCESS",
  - replace "MOR Lock Control" with "MOR Control Lock";

- in the SetVariableCheckHandlerMor() description:
  - replace @param with @param[in],
  - rewrap the comment to 80 columns.

This change cleans up commit 2f6aa774fe38 ("MdeModulePkg: Add MorLock to variable driver.", 2016-01-19).
