[PATCH for-next v5 0/6] RDMA/rxe: Replace mr page map with an xarray

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

 



This patch series replaces the page map carried in each memory region
with a struct xarray. It is based on a sketch developed by Jason
Gunthorpe. The first five patches are preparation that tries to
cleanly isolate all the mr specific code into rxe_mr.c. The sixth
patch is the actual change.

v5:
  Responded to a note from lizhijian@xxxxxxxxxxx and restored calls to
  is_pmem_page() which were accidentally dropped in earlier versions.
v4:
  Responded to a comment by Zhu and cleaned up error passing between
  rxe_mr.c and rxe_resp.c.
  Other various cleanups including more careful use of unsigned ints.
  Rebased to current for-next.
v3:
  Fixed an error reported by kernel test robot
v2:
  Rebased to 6.2.0-rc1+
  Minor cleanups
  Fixed error reported by Jason in 4/6 missing if after else.

Bob Pearson (6):
  RDMA/rxe: Cleanup mr_check_range
  RDMA/rxe: Move rxe_map_mr_sg to rxe_mr.c
  RDMA-rxe: Isolate mr code from atomic_reply()
  RDMA-rxe: Isolate mr code from atomic_write_reply()
  RDMA/rxe: Cleanup page variables in rxe_mr.c
  RDMA/rxe: Replace rxe_map and rxe_phys_buf by xarray
