will it be maped with vm_area struct ? Yes if it is accessed via mmap system call.
you know that , in the struct vm_area_struct,there is a struct vm_operations_struct * vm_ops; in this vm_operations_struct , there are open/close functions , are there necessary relations between file operations and this struct ? thanks!
what is the relation between page-cache and file operation? file operations for data access like read/write will look into page-cache first before going to disk.
