наб ad9e767657 linux: module: weld all but spl.ko into zfs.ko 
Originally it was thought it would be useful to split up the kmods
by functionality.  This would allow external consumers to only load
what was needed.  However, in practice we've never had a case where
this functionality would be needed, and conversely managing multiple
kmods can be awkward.  Therefore, this change merges all but the
spl.ko kmod in to a single zfs.ko kmod.

# When integrated in to a monolithic kernel the spl module must appear
