I think we shouldn't bind it on time but rather on whether the device is available. Maybe check that instead of schedule_timeout(10*HZ)?
BTW, we stay in TASK_UNINTERRUPTIBLE here!
+ int i; + + if (!(flags & SOMETHING_SAYING_WE_SHALL_NOT_INTERRUPT)) { + while (!path_lookup(name, LOOKUP_FOLLOW, &dummy)) { + i++; + printk(KERN_NOTICE "Root FS not yet available!\n"); + if (i > 10) + break; + + schedule_timeout(HZ/2); + } + }
or whatever.
