/* dm_target_linear.c */
/*
* Allocate target specific config data, and link them to table.
* This function is called only when, flags is not READONLY and
* therefore we can add things to pdev list. This should not a
* problem because this routine is called only from dm_table_load_ioctl.
* @argv[0] is name,
* @argv[1] is physical data offset.
