From: Zhiyuan Dai <daizhiyuan@xxxxxxxxxxxxxx> Subject: 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.
