[PATCH v2 07/17] libnvdimm: keep region data alive over namespace removal

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



nd_region device driver data will be used in the namespace i/o path.
Re-order nd_region_remove() to ensure this data stays live across
namespace device removal
