  "message": "xen/blkback: don\u0027t keep persistent grants too long\n\nPersistent grants are allocated until a threshold per ring is being\nreached. Those grants won\u0027t be freed until the ring is being destroyed\nmeaning there will be resources kept busy which might no longer be\nused.\n\nInstead of freeing only persistent grants until the threshold is\nreached add a timestamp and remove all persistent grants not having\nbeen in use for a minute.\n\nSigned-off-by: Juergen Gross \u003cjgross@suse.com\u003e\nReviewed-by: Roger Pau Monné \u003croger.pau@citrix.com\u003e\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\n",
