Yes, it is very important to have fine-grained control over what is
checkpointable and not.  We can't simply say "all sockets are OK" all at
once.  I meant this as a high-level things so that I didn't have to go
chase down the several f_ops for each in and every filesystem that is
supported.

Did you look farther down in the patches to see how this can be
overridden with an f_op?
