The Linux kernel is planning to support FALLOC_FL_WRITE_ZEROES in
fallocate(2). Add tests for the newly added fallocate
FALLOC_FL_WRITE_ZEROES command. This series depends on the changes to
xfs_io [1] that introduced the 'fwzero' command.

 - generic/764 is an extension of generic/008, it is designed to test
   page boundaries for fwzero.
 - generic/765 is an extension of generic/009, it is designed to do
   generic functions tests for fwzero.
 - generic/766 is and extension of generic/349 and generic/351, it is
   designed to test fwzero on raw block device.
 - Finally, add FALLOC_FL_WRITE_ZEROES support for fstress and fsx.

Thanks,
