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. 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 drivers/infiniband/sw/rxe/rxe_loc.h | 6 +- drivers/infiniband/sw/rxe/rxe_mr.c | 563 ++++++++++++++------------ drivers/infiniband/sw/rxe/rxe_resp.c | 105 ++--- drivers/infiniband/sw/rxe/rxe_verbs.c | 36 -- drivers/infiniband/sw/rxe/rxe_verbs.h | 32 +- 5 files changed, 362 insertions(+), 380 deletions(-) v2: Rebased to 6.2.0-rc1+ Minor cleanups Fixed error reported by Jason in 4/6 missing if after else. base-commit: bd99ede8ef2dc03e29a181b755ba4f78da2644e6 -- 2.37.2
