The original version in the 2.4 kernel has a dramatic problem leading to FS corruption, at least when used with blkmtd on CF. That's why I'm using 2.4 and a CVS snapshot, not only because it is much faster. >> To use it on a non-MTD[1] device you will need an emulation layer, >> the pseudo Block-MTD device.
