Add zfs module feature and property info to sysfs This extends our sysfs '/sys/module/zfs' entry to include feature and property attributes. The primary consumer of this information is user processes, like the zfs CLI, that need to know what the current loaded ZFS module supports. The libzfs binary will consult this information when instantiating the zfs and zpool property tables and the pool features table. This introduces 4 kernel objects (dirs) into '/sys/module/zfs' with corresponding attributes (files): features.runtime features.pool properties.dataset properties.pool Reviewed-by: Matthew Ahrens <mahrens@delphix.com> Reviewed-by: Tony Hutter <hutter2@llnl.gov> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Don Brady <don.brady@delphix.com> Closes #7706

Fix in-kernel sysfs entries The recent sysfs zfs properties feature breaks the in-kernel builds of zfs (sans module). When not built as a module add the sysfs entries under /sys/fs/zfs/.
