| H A D | dax.c | e4b3448b Fri Mar 01 13:12:41 CST 2019 Matthew Wilcox <willy@infradead.org> dax: Flush partial PMDs correctly
The radix tree would rewind the index in an iterator to the lowest index
of a multi-slot entry. The XArray iterators instead leave the index
unchanged, but I overlooked that when converting DAX from the radix tree
to the XArray. Adjust the index that we use for flushing to the start
of the PMD range.
