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

[Joel Granados Moreno]

* libparted/arch/linux.c (_mount_table_search): When we look for stuff in
  /proc/mounts, /proc/swaps and /etc/mtab, there is a possibility to
  receive none path elements.  Like "none", "tmpfs" or
  "//servername/path".  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.
