From 2374c09b1c8a883bb9b4b2fc3756703eeb618f4a Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 24 Apr 2020 08:43:36 +0200 Subject: sysctl: remove all extern declaration from sysctl.c Extern declarations in .c files are a bad style and can lead to mismatches. Use existing definitions in headers where they exist, and otherwise move the external declarations to suitable header files.
