I didn't actually write this patch myself. This did it instead:

s/anon_vma_lock/anon_vma_sem/
s/i_mmap_lock/i_mmap_sem/
s/locks/sems/
s/spinlock_t/struct rw_semaphore/

so it didn't look a big deal to redo it indefinitely.

The right patch ordering isn't necessarily the one that reduces the
total number of lines in the patchsets. The mmu-notifier-core is
already converged and can go in. The rest isn't converged at
all... nearly nobody commented on the other part (the few comments so
far were negative), so there's no good reason to delay indefinitely
what is already converged, given it's already feature complete for
certain users of the code. My patch ordering looks more natural to
me. What is finished goes in, the rest is orthogonal anyway.
