Regarding users, well the option looks like this: [ ] Enable write support (DANGEROUS) I think any user would think twice before enabling it. Regaring the maintainability: the implementation is *really* simple, and won't add much complexity. Let's not prevent someone from divising a wear level aware block filesystem and using it on top of ubiblock. And perhaps f2fs already does a good job! Keeping this support would allow someone to take the lead and get some real numbers on that. As I said, the implementation is so simple that it seems a pity to just drop it. BTW, v5 (this is v4 which I forgot to add to the subject) is already on the oven, with the fixes pointed out by Richard. -- Ezequiel GarcĂ­a, Free Electrons Embedded Linux, Kernel and Android Engineering http://free-electrons.com
