Subject: [PATCH] rbd: fix cache mode behavior
|
||
|
|
|
||
|
|
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.
