 * @f_ops: File operations associated with given dentry.
 *
 * Each gfxfs dentry has the ability for callbacks to be
 * registered with it upon allocation. In the event a
 * callback is registered, it gets executed in place of
 * the generic dcache routines. For all other operations,
 * we rely on generic routines provided by the dcache.
 *
 * Notably, the registered file operations callbacks
 * only apply to regular (S_IFREG) files.
