ver_linux: libc, input redirection to sed fails in some distros
The current implementation has been found not to work across all distros. The proposed implementation relies on 'sed' to both output the string 'Linux C Library' as well as to open '/proc/self/maps' without having to use output redirection. 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>
