This change ensures that concurrent device access including ramdisk

When resp_xdwriteread() can't allocate temporary buffer, it returns -1.
But the return value is used as scsi status code and -1 is not
interpreted as correct code.

Reading partially unwritten sectors generates a false positive logical
block reference tag check failure when DIF is enabled.
This bug is caused by missing ei_lba increment in loop of dif_verify()
when unwritten sector is skipped.

Currently, clustering support for scsi_debug is disabled. This is
because there are for_each_sg() loops which assume that each sg list
element is consisted with a single page. But enabling clustering
support, each sg list element for scsi commands can be consisted with
multiple pages.

As pseudo_primary is only used in scsi_debug.c, it should be static.

It is unnecessary to increase dif_errors in dif_verify(), because the
caller will increment it when dif_verify() detects failure.
This bug was introduced by commit beb40ea42bd6 ("[SCSI] scsi_debug:
reduce duplication between prot_verify_read and prot_verify_write")

This adds a module parameter to enable clustering.
Without enabling clustering support, the transfer length for read and
write scsi commands is limited upto 8MB when page size is 4KB and
sg_tablesize is 2048 (= SCSI_MAX_SG_CHAIN_SEGMENTS). I would like to
test commands with more than that transfe
