From: Miaohe Lin <linmiaohe@xxxxxxxxxx> Subject: mm/zswap.c: remove unused function zswap_debugfs_exit() Patch series "Cleanup and fixup for zswap". This series contains cleanups to remove unused function and avoid unnecessary copy-in at map time. Also this fixes two bugs in the function zswap_writeback_entry(). More details can be found in the respective changelogs. This patch (of 3): zswap_debugfs_exit() is unused, remove it.
