Subject: mm/page_alloc: remove unnecessary inner __get_pfnblock_flags_mask
Date: Fri, 11 Aug 2023 19:59:44 +0800
Patch series "Two minor cleanups for get pageblock migratetype".
This series contains two minor cleanups for get pageblock migratetype.
More details can be found in respective patches.
This patch (of 2):
get_pfnblock_flags_mask() just calls inline inner
__get_pfnblock_flags_mask without any extra work. Just opencode
__get_pfnblock_flags_mask in get_pfnblock_flags_mask and replace call to
__get_pfnblock_flags_mask with call to get_pfnblock_flags_mask to remove
unnecessary __get_pfnblock_flags_mask.
