The patch does somehow not what it promises.
KMountPoint::Ptr mp = KMountPoint::currentMountPoints().findByPath( path );
"KMountPoint::currentMountPoints()" promises to return mtab, ie. already used
mountpoints, so if there's "mp", it's mounted, iow. it looks like (i've just
looked at this for the first time) as if it only shortcuts for already mounted
autofs mounts, but will still statvfs on unmounted autofs mounts (mounting them
implicitly)
Ie. what the patch probably should do was to:
if (!mp) { // unmounted, avoid automounts
KMountPoint::Ptr pmp = KMountPoint::possibleMountPoints().findByPath(path);
if (pmp && pmp->mountType() == QLatin1String("autofs"))
return info;
}
