As of RHEL 7.5 the mainline fops.iterate() method was added to the file_operations structure and is correctly detected by the configure script. Normally this is what we want, but in order to maintain KABI compatibility the RHEL change additionally does the following: * Requires that callers intending to use this extended interface set the FMODE_KABI_ITERATE flag on the file structure when opening the directory. * Adds the fops.iterate() method to the end of the structure, without removing fops.readdir(). This change updates the configure check to ignore the RHEL 7.5+ variant of fops.iterate() when detected. Instead fallback to the fops.readdir() interface which will be available. Finally, add the 'zpl_' prefix to the directory context wrappers to avoid colliding with the kernel provided symbols when both the fops.iterate() and fops.readdir() are provided by the kernel.
