From 1c7e9111f4e6d6d42bc47759c9af1ef91f03ac2c Mon Sep 17 00:00:00 2001 From: Mark Harmstone Date: Tue, 17 Feb 2026 17:32:39 +0000 Subject: [PATCH] btrfs: print correct subvol num if active swapfile prevents deletion Fix the error message in btrfs_delete_subvolume() if we can't delete a subvolume because it has an active swapfile: we were printing the number of the parent rather than the target.
