From abca1c84b7575b470789c8686688b11ba3bf138d Mon Sep 17 00:00:00 2001 From: Wei Yang Date: Mon, 1 Jun 2020 21:48:58 -0700 Subject: [PATCH] mm/swapfile.c: remove the extra check in scan_swap_map_slots() scan_swap_map_slots() is only called by scan_swap_map() and get_swap_pages(). Both ensure nr would not exceed SWAP_BATCH. Just remove it.
