The serie intent is to fix unexpected paths in module's list: This happens: - when running under old / (new) wow64 - when main module is located under the syswow64 directory - the 32 bit modules are stored in LdrData (and then exposed through a couple of ways) under syswow64 (they are normally stored under system32, letting the redirection come into play when needed)
This triggers a couple of errors in winetest (as we're using c:\windows\syswow64\msinfo32.exe in many tests to trigger a wow64 process from a winetest program).
This is the fix awaited in MR!2497.
@julliard: I'm not 100% happy with the fix itself by reintroducting ref to the redirected DLLs in ntdll/PE but couldn't find a better idea.
-- v3: ntdll,wow64: Unredirect DLLs filename before storing them into LdrData. kernel32: Harden some wow64 module tests.
