From b1e904999542ad6764eafa54545f1c55776006d1 Mon Sep 17 00:00:00 2001 From: Breno Leitao Date: Tue, 8 Apr 2025 11:32:01 -0700 Subject: [PATCH] net: pass const to msg_data_left() The msg_data_left() function doesn't modify the struct msghdr parameter, so mark it as const. This allows the function to be used with const references, improving type safety and making the API more flexible.
