Re: checkpointing Indeed I did think of this, but I am fearful of blowing my schdule by trying to implement it. I'd imagine that you would store the RAM data structures in the block with the highest sequence number and attempt to find it at mount time. If you find it, great - otherwise do the normal scan. The checkpoint would have to be stored occasionally or on unmount (clean shutdown). Is there an old discussion in the archive on how best to implement this? Also, any ideas on good ways to use the interleaved and cached programming features of these big NANDs? Regards, Kent. __________________________________________________ Do You Yahoo!? Tired of spam?
