From 80c13749140284abdc23bbeed2507b7e5a3dc459 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Fri, 29 Sep 2006 01:58:51 -0700 Subject: [PATCH] [PATCH] uml: close file descriptor leaks Close two file descriptor leaks, one in the ubd driver and one to /proc/mounts. The ubd driver bug also leaked some vmalloc space. The /proc/mounts leak was a descriptor that was just never closed.
