Commit torvalds/linux@46ad0840b has removed the architecture specific rwsem source and headers leaving only the generic version. As part of this change the RWSEM_ACTIVE_READ_BIAS and RWSEM_ACTIVE_WRITE_BIAS macros were moved to the private kernel/locking/rwsem.h header. This results in a build failure because these macros were required to implement the rw_tryupgrade() compatibility function. In practice, this isn't a major problem because there are only a few consumers of rw_tryupgrade() and because consumers of rw_tryupgrade should be written to retry using rw_enter(RW_WRITER). After auditing all of the callers only dmu_zfetch() was determined not to perform a retry. It has been updated in this commit to resolve this issue. That said, the rw_tryupgrade() functionality should be considered for possible removal in a future release due to the difficultly in supporting the interface.
