2015-09-09fix ufs write vs readpage race when writing into a holeAl Viro1-2/+2
Followup to the UFS series - with the way we clear the new blocks (via buffer cache, possibly on more than a page worth of file) we really should not insert a reference to new block into inode block tree until after we'd cleared it.

2015-09-09dax: update PMD fault handler with PMEM APIRoss Zwisler1-2/+4
As part of the v4.3 merge window the DAX code was updated by Matthew and Kirill to handle PMD pages. Also as part of the v4.3 merge window we updated the DAX code to do proper PMEM flushing (commit 2765cfbb342c: "dax: update I/O path to do proper PMEM flushing"). The additional code added by the DAX PMD patches also needs to be updated to properly use the PMEM API. This ensures that after a PMD fault is handled the zeros written to the newly allocated pages are durable on the DIMMs. linux/dax.h is included to get rid of a bunch of sparse warnings.
