ver_linux: proc/modules, limit text processing to 'sed'
This patch is more of a personal preference, rather than a fix for a problem. The current implementation used a combination of both 'cat' and 'sed' to generate an unsorted list of kernel modules separated by while space. The proposed implementation uses 'sort' and 'sed' to generate a sort list of kernel modules separated by while space. Tested on: Gentoo Linux Debian 6.0.10 Oracle Linux Server release 7.1 Arch Linux openSuSE 13.2 Signed-off-by: Alexander Kapshuk <alexander.kapshuk@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
