You can do this, I tweeked the yaffs2 code to do just that:
yaffs_fs.c:
T(YAFFS_TRACE_OS,(" erase %p\n",mtd->erase));
T(YAFFS_TRACE_OS,(" read %p\n",mtd->read));
T(YAFFS_TRACE_OS,(" write %p\n",mtd->write));
T(YAFFS_TRACE_OS,(" readoob %p\n",mtd->read_oob));
T(YAFFS_TRACE_OS,(" writeoob %p\n",mtd->write_oob));
T(YAFFS_TRACE_OS,(" block_isbad %p\n",mtd->block_isbad));
T(YAFFS_TRACE_OS,(" block_markbad %p\n",mtd->block_markbad));
T(YAFFS_TRACE_OS,(" oobblock %d\n",mtd->oobblock));
T(YAFFS_TRACE_OS,(" oobsize %d\n",mtd->oobsize));
T(YAFFS_TRACE_OS,(" erasesize %d\n",mtd->erasesize));
T(YAFFS_TRACE_OS,(" size %d\n",mtd->size));
