| |
2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
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.
