Re: [PATCH v3 2/3] fs/proc/task_mmu: factor out proc_maps_private fields used by PROCMAP_QUERY

Refactor struct proc_maps_private so that the fields used by PROCMAP_QUERY ioctl are moved into a separate structure. In the next patch this allows ioctl to reuse some of the functions used for reading /proc/pid/maps without using file->private_data. This prevents concurrent modification of file->private_data members by ioctl and /proc/pid/maps readers.

The change is pure code refactoring and has no functional changes.
