Thank you for explaining it! I will send a v3. Should I add a Suggested-by tag mentioning you?Sorry for jumping in. We have reported the same bug in kernel v5.10.131 [https://lore.kernel.org/all/CANX2M5bHye2ZEEhEV6PUj1kYL2KdWYeJtgXw8KZRzwrNpLYz+A@mail.gmail.com (local)]. We have been suggested to join this discussion so that we can have appropriate meta-information injected in this patch’s commit message to make sure that it gets backported to v5.10.y. Therefore, we would like to be in the loop so that we can offer help in the process, if needed.As you are suggesting for backporting, I should CC the stable list, or mail after it gets merged. You have reproduced it on v5.10, but the change seems to be introduced by c73be61cede5 ("pipe: Add general notification queue support"), which got in at v5.8. So should it be backported till v5.8 instead?
There are no active supported kernels other than the ones listed on kernel.org, so 5.8 doesn't make much sense here, only 5.10 and 5.15 and 5.18 at the moment. thanks, greg k-h
