Currently, while mapping or unmapping pages for ODP, the umem mutex is locked

hundreds of nsecs. This makes a significant impact when mapping or unmapping few

To avoid this, the mutex should be locked only
This patchset contains small changes that improve the performance of memory
map updates.
The patches reduce the execution time of ib_umem_odp_unmap_dma_pages when
invalidating 4MB of memory from 46us to 13us. This amounts to a reduction of
about 30% in the total execution time of the invalidation
While unmapping an ODP writable page, the dirty bit of the page is set. In
order to do so, the head of the compound page is found.
Currently, the compound head is found even on non-writable pages, where it is
never used, leading to unnecessary cpu barrier that impacts performance.
