dm-verity-target.c里的verity_target结构体里的map函数是在哪里被调用的呢？

在drivers/md/dm.c里的__map_bio()

static blk_qc_t __map_bio(struct dm_target_io *tio)
    r = ti->type->map(ti, clone);

 

static struct target_type verity_target = {
    .name        = "verity",
    .version    = {1, 4, 0},
    .module        = THIS_MODULE,
    .ctr        = verity_ctr,
    .dtr        = verity_dtr,
    .map        = verity_map,
    .status        = verity_status,
    .prepare_ioctl    = verity_prepare_ioctl,
    .iterate_devices = verity_iterate_devices,
    .io_hints    = verity_io_hints,
};
