Subject: [PATCH 5.7 343/477] NTB: perf: Dont require one more memory window than number of peers
From: Logan Gunthorpe <logang@...tatee.com>
[ Upstream commit a9c4211ac918ade1522aced6b5acfbe824722f7d ]
ntb_perf should not require more than one memory window per peer. This
was probably an off-by-one error.
Fixes: 5648e56d03fa ("NTB: ntb_perf: Add full multi-port NTB API support")
