Paul Gofman (@gofman) commented about dlls/ntdll/ntdll.spec:
# Filesystem @ stdcall -syscall wine_nt_to_unix_file_name(ptr ptr ptr long) @ stdcall -syscall wine_unix_to_nt_file_name(str ptr ptr)
+# Memory management +@ stdcall -syscall wine_unix_get_min_large_page_size(ptr)
This shouldn't be added as a custom Wine syscall. There is at least LargePageMinimum in USER_SHARED_DATA which can be tested and filled. There also might be a way to get that through some NtQuerySystemInformation() although I don't know offhand if there is or what information class it can be. user_shared_data is already used in kernelbase so I guess using LargePageMinimum should be fine.
