In commit 0d72b92883c651a11059d93335f33d65c6eb653b, a new u32 argument for the request_mask was added to generic_fillattr. This is the same request_mask for statx that's present in the most recent API implemented by zpl_getattr_impl. This commit conditionally adds it to the zpl_generic_fillattr(...) macro, as well as the zfs_getattr_fast(...) implementation, when configure determines it's present in the kernel's generic_fillattr(...). Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Coleman Kane <ckane@colemankane.org> Closes #15263
