  ext4: fix kernel doc warnings (2022-03-15 17:45:36 -0400)

----------------------------------------------------------------
Fix some bugs in converting ext4 to use the new mount API, as well as
more bug fixes and clean ups in the ext4 fast_commit feature (most
notably, in the tracepoints).  In the jbd2 layer, the t_handle_lock
spinlock has been removed, with the last place where it was actually
needed replaced with an atomic cmpxchg.
