[parted-devel] [PATCH] Dont try to stat stuff that we know does not exist.

[Joel Granados Moreno]

    modified:   libparted/arch/linux.c:  When we look for stuff in
    /proc/mounts, /proc/swaps and /etc/mtab, there is a possibility to
    receive none path elements.  Like "none" or "tmpfs".  We are making
    a system call for each of these strings when it can be easily
    avoided.  This is most noticeable in situations that heavily use
    libparted, like the fedora installer.
