| |
The purpose of CONFIG_IDEDISK_STROKE is to make the setmax utility superfluous. However, I find that unclipping large disks fails because idedisk_read_native_max_address_ext() is called before probe_lba_addressing(), which means that drive->addressing is not yet set, and the high order part of the disk size is not read. Thus, probe_lba_addressing() should be moved up in ide-disk.c, for example

[this was for some variant on linux-2.4.18-pre7-ac3, but no doubt a similar patch applies to all kernels with IDE patch] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
