That is especially true for > in-kernel pseudo filesystems. I'm still amazed at this statement. "Wanting to export" is not something for the file system to decide on in any kind of sane layering. The file systems exports features, and layers higher in the stack make use of it. We just need to be precise in describing In-kernel code will then we so nice to respect it. But for userspace even then all bets are off. _______________________________________________ Linux-f2fs-devel mailing list Linux-f2fs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
