Description

The zfsonlinux feature large_dnode is not yet supported by the loader.

This is the same change as posted for FreeBSD: https://reviews.freebsd.org/D12288

At the moment the only usable large_dnode feature support is from zfsonlinux implementation, so the way to test this update is to create pool and test the reader.

tested with: zfs set dnsize=auto and then did copy some data into dataset, checked which files got dnsize > 512 and verified the loader can read those files.

Also zfs set dnsize=1k, did use setfattr to set value < 512 and value > 1k, to verify file without and with spill blocks. The pool and dataset setup was done with zol rescue ISO, read test with loader.efi.
