Really, no response? Again?

Why doesn't that surprise me if sending a bug report to Red Hat not
using their kernel,... Thanks a lot! So this is how discrimination feels
like,...


Have you checked your problem exists in the latest upstream kernel ?

If you are resolving issue with kernel 3.12 - it's likely a thing for your distribution and its maintenance support?

Upstream (and this is upstream ml) is close to release 4.1 kernel - so you are fixing couple years old issue? What kind of action do you expect ?

Hi dm developers,

we hit the srcu warning in cleanup_srcu_struct() when removing
dm-multipath devices. We run v3.12.40 but there is no change compared to
v3.12.44 in drivers/md/dm.c or kernel/srcu.c.

Would the following upstream commit fix this?

63a4f06 dm: fix add_disk() NULL pointer due to race with free_dev()

Thanks,
Sebastian
