From 2281f797f5524abb8fff66bf8540b4f4687332a2 Mon Sep 17 00:00:00 2001 From: Barry Song Date: Mon, 24 Aug 2020 11:03:09 +1200 Subject: mm: cma: use CMA_MAX_NAME to define the length of cma name array CMA_MAX_NAME should be visible to CMA's users as they might need it to set the name of CMA areas and avoid hardcoding the size locally. So this patch moves CMA_MAX_NAME from local header file to include/linux header file and removes the hardcode in both hugetlb.c and contiguous.c.
