From 4ca8e03cf2bfaeef7c85939fa1ea0c749cd116ab Mon Sep 17 00:00:00 2001 From: Josef Bacik josef@toxicpanda.com Date: Thu, 24 Aug 2023 16:59:04 -0400 Subject: [PATCH] btrfs: check for BTRFS_FS_ERROR in pending ordered assert
If we do fast tree logging we increment a counter on the current transaction for every ordered extent we need to wait for. This means we expect the transaction to still be there when we clear pending on the ordered extent. However if we happen to abort the transaction and clean it up, there could be no running transaction, and thus we'll trip the "ASSERT(trans)" check. This is obviously incorrect, and the code properly deals with the case that the transaction doesn't exist. Fix this ASSERT() to only fire if there's no trans and we don't have BTRFS_FS_ERROR() set on the file system.
