I don't think this is the right approach. Just opening a file with O_RDWR shouldn't take it out of inline mode; an actual write (or fault) should be required to uninline it. > This makes it easier to convert to using the netfs library for VM write > hooks. I don't understand. You're talking about the fault path? Surely the filesystem gets called with the vm_fault parameter only, then calls into the netfs code, passing vmf and the operations struct? And ceph could uninline there.
