Many places in the kernel have a flow where userspace will create some object and that object will need to connect to the subsystem's mmu_notifier subscription for the duration of its lifetime.
In this case the subsystem is usually tracking multiple mm_structs and it is difficult to keep track of what struct mmu_notifier's have been allocated for what mm's.
Since this has been open coded in a variety of exciting ways, provide core functionality to do this safely.
This approach uses the strct mmu_notifier_ops * as a key to determine if
s/strct/struct
Yes, thanks for all of this, I like having comments, but I'm a terrible proofreader :(
