 Modified Files:
 	src/external/cddl/osnet/dist/uts/common/fs/zfs: dsl_scan.c
 
 Log Message:
 reduce stack usage in dsl_scan_recurse() - allocate memory for
 temporary zbookmark_phys_t using kmem_alloc() rather than stack;
 this recuses several times usually, and this saves 2x
 sizeof(zbookmark_phys_t) == 64 bytes per recursion
