[$] A NILFS2 score card

A recurring theme in the comments on various articles announcing the new f2fs "flash-friendly" filesystem was that surely some other filesystem might already meet the need, or could be adjusted to meet the need, rather than creating yet another new filesystem. This is certainly an interesting question, but not one that is easy to answer. Neil Brown looks at the question of whether NILFS2 might be a candidate for a flash-focused filesystem in an article from this week's Kernel page.
