Hello! I had a question about disabling the block layer for SCSI devices. We have an embedded device, and it runs 2.4.30. We need to be able to support a lot of SCSI devices (in the thousands) for our device, and we talk to the devices via SG. We are facing a memory allocation problem after discovering a few thousand devices. For every device, there seems to be a lot of memory allocated in the block layer. This memory includes cache memory (which IIRC is reclaimable by the kernel memory subsystem when it needs it) and also pages that are used for the alloc_pages pool. My questions were relating to disabling the block layer for the devices. We always talk direct passthrough to the storage(except the local hard disk), and do not need the block layer at all. 1. Is there a way to disable the block layer for specific devices? 2. If yes, how can that be done, and are there any gotchas associated with that? Thanks!
