Warner Losh 47aeda7b70 geom_disk: use a preallocated geom_event for disk destruction. ... Preallocate a geom_event (using the new geom_alloc_event) when we create a disk. When we create the disk, we're going to be in a sleepable context, so we can always allocate this extra bit of memory. Then use this preallocated memory to free the disk. CAM can try to free the disk from an unsleepable context if there was I/O outstanding when the disk was destroyted (say because the SIM said it had gone away). The I/O context isn't sleepable. Rather than trying to invent a retry mechanism and making sure all the other geom_disk consumers did it properly, preallocating the event ensure that the geom_disk will be properly torn down, even when there's memory pressure when the disk departs.
