[PATCH v2 0/6] Improvements for dump_page()

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

Thanks to everyone for your feedback on v1.  I haven't added any acks
from v1 because most of the patches have changed substantially from v1.

Here's a sample dump of a pagecache tail page with all of the patches applied:
