Subject: [PATCH v8 0/9] DAX fsync/msync support
Changes since v7 [1]:
1) Update patch 1 so that we initialize bh->b_bdev before passing it to
get_block() instead of working around the fact that it could still be NULL
after get_block() completes. (Dan)
2) Add a check to dax_radix_entry() so that we WARN_ON_ONCE() and exit
gracefully if we find a page cache entry still in the radix tree when
trying to insert a DAX entry.
This series replaces v7 in the MM tree and in the "akpm" branch of the next
tree. A working tree can be found here:
