XFS File-System Updates For The Linux 4.9 Kernel

Dave Chinner has submitted his XFS file-system updates for the Linux 4.9 kernel. This time around most of the changes are internal to the open-source file-system rather than boasting new end-user features.

XFS for Linux 4.9 has improvements to the iomap-based DAX infrastructure, iomap fixes and changes, more efficient XFS delayed allocation using iomap, preparation patches for upcoming reflink support, and other prep changes and internal improvements.
