Subject: mm/ksm: rename variable mm_slot to ksm_slot in unmerge_and_remove_all_rmap_items
Date: Sun, 28 Apr 2024 18:06:16 +0800
To distinguish ksm_mm_slot and mm_slot for better code readability, rename
ksm_mm_slot variable as ksm_slot in function
unmerge_and_remove_all_rmap_items. No function changes.
