strcpy() is deprecated; assignment can be used instead which theoretically/potentially increases speed as a function call is removed. Straight assignment works because the strings are not null-terminated which means they don't strictly require a str(s)cpy call. No functional changes intended. Link: https://github.com/KSPP/linux/issues/88 Suggested-by: Theodore Ts'o <tytso@xxxxxxx> Signed-off-by: Ethan Carter Edwards <ethan@xxxxxxxxxxxxxxxxx> --- There's an ongoing effort to remove calls to strcpy throughout the kernel. Link: https://github.com/KSPP/linux/issues/88 --- Changes in v2: - completely remove the call to strcpy and replace it with assignment off of Theo's suggestion.
