From 66407f3b535e5a6f4ba742173b82a393bc8d2d25 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 21 Jul 2020 10:22:32 -0400 Subject: [PATCH] btrfs: flush delayed refs when trying to reserve data space We can end up with freed extents in the delayed refs, and thus may_commit_transaction() may not think we have enough pinned space to commit the transaction and we'll ENOSPC early. Handle this by running the delayed refs in order to make sure pinned is uptodate before we try to commit the transaction.
