The shm already has the vma iterator in position for a write. do_vmi_munmap() searches for the correct position and aligns the write, so it is not the right function to use in this case. The shm VMA tree modification is similar to the brk munmap situation, the vma iterator is in position and the VMA is already known. This patch generalizes the brk munmap function do_brk_munmap() to be used for any other callers with the vma iterator already in position to munmap a VMA.
