added the full file for more context. Also merged TUNABLE and SYSCTL_INT into one command.

I dont see this patch in stable 10. Is there a reason this diff was not committed to stable 10 ? I am having a conflict when I try to merge https://reviews.freebsd.org/rS303855 to stable 10 ?

Thanks Pho .. your test program works for me. I can hit the issue consistently .

This looks good. I have updated the review with the latest one. ( was having some issues with the base review being old so your patch was not applying clean to the already existing review. modified the patch a little to suit the review )

Oh thanks. . I was trying to figure out the last part so that helps :) Will have a closer look at your new patch. For some reason I am unable to create a panic with the test program you provided even after leaving it to run for long enough.

Thanks for the comments. I will be adding the PCB_LOCK to the diff and it looks fine as the order between the LINK_LOCK and PCB lock can be maintained. I will compile a patch tom after some testing . Looks something like this .

adjusted the diff as per comments.

Adding more context to the diff with the whole file.
