Chao Yu 46d4246d8d f2fs: use f2fs_{down, up}_(read, write}_trace() for nat_tree_lock ... Under heavy workloads or during background GC/fallocate operations, nat_tree_lock can experience high lock contention between background readers (e.g. f2fs_get_node_info() in gc_data_segment) and writers (e.g. flush_nat_entries, set_node_addr, shrinker).
