ibmvscsis: Fix the incorrect req_lim_delta commit 75dbf2d36f6b122ad3c1070fe4bf95f71bbff321 upstream. The current code is not correctly calculating the req_lim_delta. We want to make sure vscsi->credit is always incremented when we do not send a response for the scsi op. Thus for the case where there is a successfully aborted task we need to make sure the vscsi->credit is incremented. v2 - Moves the original location of the vscsi->credit increment to a better spot. Since if we increment credit, the next command we send back will have increased req_lim_delta. But we probably shouldn't be doing that until the aborted cmd is actually released. Otherwise the client will think that it can send a new command, and we could find ourselves short of command elements. Not likely, but could happen. This patch depends on both: commit 25e78531268e ("ibmvscsis: Do not send aborted task response") commit 98883f1b5415 ("ibmvscsis: Clear left-over abort_cmd pointers") Signed-off-by: Bryant G.
