I went this route because Android heavily restricts ioctl() permissions and we needed broader access for this to work within the framework. It’s definitely a pragmatic choice just to get it running in production. If ioctl() is a right way for upstream, I'm happy to change this patch. By the way, I really don't understand why all the messages are so offensive, even without trying to understand the problem or guiding right directions. > > > I think at some point we just need to stop taking f2fs updates likes > > this. > > Well, that's ultiamtely up to Linus.
