From 51cf07a7b6cd99d9b910932e2af4e7282782e3fe Mon Sep 17 00:00:00 2001 From: Mao Wenan Date: Tue, 16 Apr 2019 12:06:51 +0800 Subject: xenbus: drop useless LIST_HEAD in xenbus_write_watch() and xenbus_file_write() Drop LIST_HEAD where the variable it declares is never used. The declarations were introduced with the file, but the declared variables were not used.
