Hi, please add patch 881a3a11c2b8 ("btrfs: fix return value mixup in btrfs_get_extent") to 4.19 tree. It's a fixup for patch 6bf9e4bd6a27 ("btrfs: inode: Verify inode mode to avoid NULL pointer dereference"). I don't see it queued yet and the patch is tagged for 5.4, this is just a heads up so it's not forgotten. All the related patches: 6bf9e4bd6a27 ("btrfs: inode: Verify inode mode to avoid NULL pointer dereference") 9f7fec0ba891 ("Btrfs: fix selftests failure due to uninitialized i_mode in test inodes") 881a3a11c2b8 ("btrfs: fix return value mixup in btrfs_get_extent") >From 5.4 up it's fine. Thanks.
