No, but there are usage patterns where lots of data are rewritten even though the free (and dirty) space is more than the size of 6 erase blocks. If you have 12 blocks which are _half_ full because your usage pattern tends to leave you with a mix of live and dead data, we have to garbage-collect. If you have 6 blocks which are completely empty because you don't have still-valid nodes interleaved between all the stuff you deleted, that's ideal. -- dwmw2 To unsubscribe from this list: send the line "unsubscribe jffs-dev" in the body of a message to [email protected]
