Don't include the compatibility code in linux/*_compat.h in the public header sys/types.h. This causes problems when an external code base includes the ZFS headers and has its own conflicting compatibility code. Lustre, in particular, defined SHRINK_STOP for compatibility with pre-3.12 kernels in a way that conflicted with the SPL's definition. Because Lustre ZFS OSD includes ZFS headers it fails to build due to a '"SHRINK_STOP" redefined' compiler warning. To avoid such conflicts only include the compat headers from .c files or private headers. Also, for consistency, include sys/*.h before linux/*.h then sort by header name.
