Jan Beulich 3a1ca9bd4f xen-blkback: don't leak persistent grants from xen_blkbk_map() ... commit a846738f8c3788d846ed1f587270d2f2e3d32432 upstream. The fix for XSA-365 zapped too many of the ->persistent_gnt[] entries. Ones successfully obtained should not be overwritten, but instead left for xen_blkbk_unmap_prepare() to pick up and put. This is XSA-371.
