From c4e54a65711688e78e81d6e2720f19f0747eb176 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Thu, 26 Jan 2023 16:00:56 -0500 Subject: btrfs: replace clearing extent buffer dirty bit with btrfs_clean_block Now that we're passing in the trans into btrfs_clean_tree_block, we can easily roll in the handling of the !trans case and replace all occurrences of if (test_and_clear_bit(EXTENT_BUFFER_DIRTY, &eb->bflags)) clear_extent_buffer_dirty(eb); with btrfs_tree_lock(eb); btrfs_clean_tree_block(eb); btrfs_tree_unlock(eb); We need the lock because if we are actually dirty we need to make sure we aren't racing with anything that's starting writeout currently. This also makes sure that we're accounting fs_info->dirty_metadata_bytes appropriately.
