From 96de8f85203147e3d1e646da891307fa3e462c32 Mon Sep 17 00:00:00 2001 From: Bharadwaj Raju Date: Fri, 27 Jun 2025 22:11:29 +0530 Subject: [PATCH] bcachefs: mark invalid_btree_id autofix Checking for invalid IDs was introduced in 9e7cfb35e266 ("bcachefs: Check for invalid btree IDs") to prevent an invalid shift later, but since 141526548052 ("bcachefs: Bad btree roots are now autofix") which made btree_root_bkey_invalid autofix, the fsck_err_on call didn't do anything. We can mark this err type (invalid_btree_id) autofix as well, so it gets handled.
