Subject: [RFC] improve malloc for large filesystems - prefetching

Hi,

Here is a refreshed patch to improve bitmap loading.
This should significantly improve bitmap loading, especially for flex groups as it tries to load all bitmaps within a flex.group instead of one by one synchronously.
Please review

Thanks, Alex
