How shall we proceed? Do you > want me to resend to you with David's Signed-off-by? Do I see it correctly that this will be 6.12.y and 6.13.y specific backports since the code in mainline changed substantially with e2d46f2ec332 ("netfs: Change the read result collector to only use one work item") and so your change does not apply there anymore? I'm asking since we got a bug report in Debian which seems to idicate it might have the same root cause as you report, and it is at https://bugs.debian.org/1098698 . Regards, Salvatore
