This needs to be done in caller application context. As part of asynchronous management API rework, volume_open callback was moved to kernel worker thread context. To work around this, atomic parameters are now read before cache attach/load/probe and provided to bottom volume via volume params. Signed-off-by: Adam Rutkowski <adam.j.rutkowski@intel.com>
