the syscall. Anything beyond st_mtim was therefore not filled in. Fixes the incorrectly shown creation times in Tracker. * The BStatable::GetStat() solution was not sufficient yet. We still have to provide the old GetStat() symbol for BNode and BEntry, since those could be used by old applications/libraries. We also still have to implement the old GetStat() slots in the derived classes, but don't need to implement it in the base class (was purely virtual before and is private now). * The old BStatable::_OhSoStatable1() slot function was not implemented correctly. Calling the virtual function at the vtable slot obviously results in an infinite recursion. The correct implementation would make use of the Perform() method, but Be didn't provide one for BStatable, so we have to use the old GetStat() method. Fixed #3960. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30851 a95241bf-73f2-0310-859d-f6bbb57e9c96
