Since ODP had a single struct mmu_notifier located in the ucontext it could only handle a single MM at a time, and this prevented it from using the new owning_mm system. With the prior rework it is now simple to let ODP track multiple MMs per ucontext, finish the job so that the per_mm is allocated on a mm by mm basis, and freed when the last umem is dropped from the ucontext. As a side effect the new saner locking removes the lockdep splat about nesting the umem_rwsem between mmu_notifier_unregister and ib_umem_odp_release. It also makes ODP work with multiple processes, across, fork, etc. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com> |
