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.
