| Subject: nfs: Add "lookupcache" to displayed mount options |
| |
| From: Patrick J. LoPresti <lopresti@gmail.com> |
| |
| commit 9b00c64318cc337846a7a08a5678f5f19aeff188 upstream. |
| |
| Running "cat /proc/mounts" fails to display the "lookupcache" option. |
| This oversight cost me a bunch of wasted time recently. |
| |
| The following simple patch fixes it. |
