xfs: support T10 protection information

Browse source

Add support for generating / verifying protection information in the file
system.  This is largely done by simply setting the IOMAP_F_INTEGRITY
flag and letting iomap do all of the work.  XFS just has to ensure that
the data read completions for integrity data are run from user context.

For zoned writeback, XFS also has to generate the integrity data itself
as the zoned writeback path is not using the generic writeback_submit
implementation.
