128 * drive_is_flashcard - check for compact flash
129 * @drive: drive to check
130 *
131 * CompactFlash cards and their brethern pretend to be removable
132 * hard disks, except:
133 * (1) they never have a slave unit, and
134 * (2) they don't have doorlock mechanisms.
135 * This test catches them, and is invoked elsewhere when setting
136 * appropriate config bits.
137 *
138 * FIXME: This treatment is probably applicable for *all* PCMCIA (PC CARD)
139 * devices, so in linux 2.3.x we should change this to just treat all
140 * PCMCIA drives this way, and get rid of the model-name tests below
141 * (too big of an interface change for 2.4.x).
142 * At that time, we might also consider parameterizing the timeouts and
143 * retries, since these are MUCH faster than mechanical drives. -M.Lord
