From 79cd420248c776005d534416bfc9b04696e6c729 Mon Sep 17 00:00:00 2001 From: Zhiyuan Dai Date: Tue, 4 May 2021 18:39:57 -0700 Subject: mm/zswap.c: switch from strlcpy to strscpy strlcpy is marked as deprecated in Documentation/process/deprecated.rst, and there is no functional difference when the caller expects truncation (when not checking the return value). strscpy is relatively better as it also avoids scanning the whole source string.
