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. v6: Respond to a comment from Jason and moved the #if defined CONFIG_64BIT outside of the rxe_mr_do_atomic_write() function. I realized that the #else case isn't needed since it will never be called so if someone does try it will fail at compile/link time. 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 drivers/infiniband/sw/rxe/rxe_loc.h | 13 +- drivers/infiniband/sw/rxe/rxe_mr.c | 622 +++++++++++++++----------- drivers/infiniband/sw/rxe/rxe_resp.c | 118 ++--- drivers/infiniband/sw/rxe/rxe_verbs.c | 36 -- drivers/infiniband/sw/rxe/rxe_verbs.h | 37 +- 5 files changed, 422 insertions(+), 404 deletions(-) base-commit: 1ec82317a1daac78c04b0c15af89018ccf9fa2b7 -- 2.37.2
