>From Jason,
Restricting ODP to use only a single process and mm doesn't really make
any sense, the data structure work to fix that is fairly straightforward
and allows ODP to also stop using tgid as well.
This series also cleans up a few things in the ODP code along the way
to make it easier to make the datastructure change, and fixes a bunch
of locking race conditions and other mistakes that syzkaller and lockdep
finds in this code.
Thanks
Jason Gunthorpe (9):
RDMA/umem: Use ib_umem_odp in all function signatures connected to ODP
RDMA/umem: Make ib_umem_odp into a sub structure of ib_umem
RDMA/umem: Get rid of struct ib_umem.odp_data
RDMA/umem: Move all the ODP related stuff out of ucontext and into
per_mm
RDMA/umem: Use umem->owning_mm inside ODP
RDMA/umem: Get rid of per_mm->notifier_count
RDMA/umem: Handle a half-complete start/end sequence
RDMA/umem: Avoid synchronize_srcu in the ODP MR destruction path
RDMA/uverbs: Get rid of ucontext->tgid
