Description

The registration portion of STMF calls kmem_alloc() with constants for LU kstats (STMF_KSTAT_LU_SZ) and for the port kstats (STMF_KSTAT_TGT_SZ). The corresponding kmem_free() calls, however, are both being fed the kstat's ks_data_size, which breaks on kmem_debug=0xf when ks_data_size is altered (legally, by the kstat subsystem).
