Specific problem.
for recovery reasons I need to keep current mmaping in user space, but
to force Kernel to invalidate pages assigned to given file descriptor.
I tried wild-guess  with 'zap_page_range' and
'invalidate_inode_pages'.... does not work.

Is there already way to remove all pages linked to specific inode?

Something like 'do_mremap' will be perfect, only if I can overlap old
and new address....

Thanks in advance
