From 92ece28072f18f30099770c5d4b8e300ea6820fa Mon Sep 17 00:00:00 2001 From: Liu Jian Date: Sat, 16 Apr 2022 18:58:00 +0800 Subject: [PATCH] net: Change skb_ensure_writable()'s write_len param to unsigned int type Both pskb_may_pull() and skb_clone_writable()'s length parameters are of type unsigned int already. Therefore, change this function's write_len param to unsigned int type.
