This drops debian/patches/pve/0005-PVE-Config-smm_available-false.patch (and renumbers the remaining patches) From what I could gather, this patch was originally added due to issues with old kernels. Now we have users which seem to run into issues *with* the patch. All this does is toggle an option, and it's available via a qemu CLI option anyway, so if dropping this patch causes issues for some people we can just add an option to qemu-server & UI control smm explicitly.

Subject: [PATCH] PVE: [Config] rbd: block: rbd: disable
|
|
rbd_cache_writethrough_until_flush
|
|
|
|
Either the cache mode asks for a cache or not. There's no
|
|
point in having a "temporary" cache mode. This option AFAIK
|
|
was introduced as a hack for ancient virtio drivers. If
|
|
anything, we should have a separate option for it. Better
|
|
yet, VMs affected by the related issue should simply
|
|
explicitly choose writethrough.
