From 943f229e9608104c11bf9a230883dbd121323532 Mon Sep 17 00:00:00 2001 From: Zhiyuan Dai Date: Thu, 29 Apr 2021 22:57:55 -0700 Subject: [PATCH] mm/dmapool: 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.
