From daefe4d435d75118af302dae650547b8b760da0b Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Thu, 8 Jun 2023 11:27:42 +0100 Subject: btrfs: rename enospc label to out at balance_level() At balance_level() we have this 'enospc' label where we jump to in case we get an error at several places. However that error is certainly not -ENOSPC in call cases, it can be -EIO or -ENOMEM when reading a child extent buffer for example, or -ENOMEM when trying to record tree mod log operations. So to make this less confusing, rename the label to 'out'.
