[vdr] making VDR ext4-ready

Hi,

today I've read an interesting article about ext4: http://www.heise.de/open/Das-Linux-Dateisystem-Ext4--/artikel/138431 (german, but there is also an english version). The new file system seems to be better for large files, as VDR-recordings are. Files up to 512 MB can be saved with just 1 inode, instead of a half Megabyte of inodes in ext3.

So ext4 seems to be perfect for a video-partition, but to make it more perfect, it would be nice if VDR could use the fallocate()-systemcall as mentioned in the article. This would prevent fragmentation in the file system.

For more information you should read the article ;)
