Hi Jerome,
Thanks for updating the documentation for hmm_devmem_ops.
I have an inquiry about the "fault" callback, though. The documentation
says "Returns: 0 on success", but can the driver set any VM_FAULT_*
flags? For instance, the driver might want to set the VM_FAULT_MAJOR
flag to indicate that a heavy-weight page migration has happened on the
page fault.
If that is possible, can you please update the documentation and list
the flags that are permitted in the callback's return value?
Thanks!
