zhangyi (F) 5eac8aff61 jbd2: improve comments about freeing data buffers whose page mapping is NULL 
commit 780f66e59231fcf882f36c63f287252ee47cc75a upstream.

Improve comments in jbd2_journal_commit_transaction() to describe why
we don't need to clear the buffer_mapped bit for freeing file mapping
buffers whose page mapping is NULL.
