Christoph Hellwig	da9baa5470	exportfs,nfsd: rework checking for layout-based block device access support ... Currently NFSD hard codes checking support for block-style layouts. Lift the checks into a file system-helper and provide a exportfs-level helper to implement the typical checks. This prepares for supporting block layout export of multiple devices per file system.

Christoph Hellwig	61eb48f515	exportfs: don't pass struct iattr to ->commit_blocks ... The only thing ->commit_blocks really needs is the new size, with a magic -1 placeholder 0 for "do not change the size" because it only ever extends the size.

Christoph Hellwig	d5758c31a8	exportfs: split out the ops for layout-based block device access ... The support to grant layouts for direct block device access works at a very different layer than the rest of exports. Split the methods for it into a separate struct, and move that into a separate header to better split things out. The pointer to the new operation vector is kept in export_operations to avoid bloating the super_block.
