[patch 092/178] mm/dmapool: switch from strlcpy to strscpy

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
