From 06aa8b8a0345c78f4d9a1fb3f852952b12a0e40c Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Fri, 1 Aug 2014 12:29:44 +0200 Subject: inet: frags: rename last_in to flags The last_in field has been used to store various flags different from first/last frag in so give it a more descriptive name: flags.
