dax: add tracepoints to dax_writeback_mapping_range()
Add tracepoints to dax_writeback_mapping_range(), following the same
logging conventions as the rest of DAX.
Here is an example writeback call:
msync-1085 [006] ....
200.902565: dax_writeback_range: dev 259:0 ino 0x1003 pgoff 0x200-0x2ff
msync-1085 [006] ....
200.902579: dax_writeback_range_done: dev 259:0 ino 0x1003 pgoff 0x200-0x2ff
