Paolo Bonzini 32a8811ff1 target: support zero allocation length in REQUEST SENSE ... Similar to INQUIRY and MODE SENSE, construct the sense data in a buffer and later copy it to the scatterlist. Do not do anything, but still clear a pending unit attention condition, if the allocation length is zero. However, SPC tells us that "If a REQUEST SENSE command is terminated with CHECK CONDITION status [and] the REQUEST SENSE command was received on an I_T nexus with a pending unit attention condition (i.e., before the device server reports CHECK CONDITION status), then the device server shall not clear the pending unit attention condition." Do the transport_kmap_data_sg early to detect this case. It also tells us "Device servers shall not adjust the additional sense length to reflect truncation if the allocation length is less than the sense data available", so do not do that! Note that the err variable is write-only. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>		13 years ago
