A log structured fs without gc is about as useful as a bicycle without a front wheel. gc is a gotta-have feature. Both JFFS2 and YAFFS are log structured fs. Both have gc. > > Any comments, insights or criticism is warmly welcome. Congratulations on tackling a file system project. In many ways, fs are the most challenging parts of an OS, IMHO. I'll tae some time to look into this further. -- Charles - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
