Some of the drivers (AHCI was mentioned to me as a culprit) take a long time to discover all the devices attached to them. Even for ones which are relatively quick, if you put a lot of them in a machine, it will take a long time in aggregate. This can be fixed by adding support for asynchronous scsi scans, which causes the time-consuming portions of initialisation to take place in threads. Signed-off-by: Matthew Wilcox <matthew@xxxxxx>
The time-consuming portion already takes place in a thread. Do you mean multiple threads? Or, ATA's scan is in one thread, while work continues in other threads?
Patch seems sane, provided that I am educated a bit :) Jeff - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
