From 2c536799f1bde905bbacf7af3aa6be3f4de66005 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Mon, 3 Oct 2011 23:22:41 -0400 Subject: btrfs: btrfs_drop_snapshot should return int Commit cb1b69f4 (Btrfs: forced readonly when btrfs_drop_snapshot() fails) made btrfs_drop_snapshot return void because there were no callers checking the return value. That is the wrong order to handle error propogation since the caller will have no idea that an error has occured and continue on as if nothing went wrong.
