Hi Greg, This is a bcache patch upstreamed in Linux v5.19, it fixes the undefined stack state which I feel it should go into stable tree as well. I go through all the stable releases since Linux v5.10, based on current stable tree maintenance status, this patch should be applied to the following stable kernel releases, - longterm: 5.10, 5.15 - 5.17, 5.18 Please consider to take it for the above stable kernels. Thank you in advance for taking care of them.
