Sure.
My driver has privately managed non LRU pages which gets mapped into user space
process page table through f_ops->mmap() and vmops->fault() which then updates
the file RMAP (page->mapping->i_mmap) through page_add_file_rmap(page). One thing
to note here is that the page->mapping eventually points to struct address_space
(file->f_mapping) which belongs to the character device file (created using mknod)

But when I stop the NFS service, or shutdown A, which means all the

Hmm, page_add_file_rmap is not exported function. How does your driver can use it?
Do you use vm_insert_pfn?

How does libvirt interaction with KVM to create a VM?
All,
These days I am trying to understand the interaction relationship
between the libvirt and KVM kernel module, eg. kvm_intel.ko.
We know that KVM kernel module expose an entry in form of device file
"/dev/kvm" which can be accessed by user space application to control,
for example, create a VM using KVM_CREATE_VM with help of ioctl.
Now let's say the tool virsh based upon
