Mike Snitzer 45e0e1ec14 NFSD: filecache: add STATX_DIOALIGN and STATX_DIO_READ_ALIGN support ...

[ Upstream commit d11f6cd1bb ]

Use STATX_DIOALIGN and STATX_DIO_READ_ALIGN to get DIO alignment
attributes from the underlying filesystem and store them in the
associated nfsd_file. This is done when the nfsd_file is first
opened for each regular file.
