Thank you! > Just so I'm clear, this is in addition to Chuck's "Handle TCP socket sends with kernel_sendpage() again" patch from bz #209439 (which I think is now in 5.11 rc)? Or you want to see what this patch looks like on it's own without that (e.g. v5.10)? Please include the "Handle TCP socket sends with kernel_sendpage() again" fix. Or, you can pull a recent stable kernel, I think that fix is already in there. -- Chuck Lever
