Quoting the thread from 4 years ago: I'd love to see the readdir() interface cleaned up, yes please. > Comments? Hmm. Do we want to think about letting callers copy the name to userspace in fragments? I was looking at current readdir paths and saw that btrfs has an annoying wrinkle that its directory entries might be in large blocks that span disjoint pages. So it copies them to a kmalloced()ed buffer to pass to filldir(). Maybe it wouldn't be worth having to track incomplete entries in the core, but it'd be nice to get rid of this copy in btrfs. (btrfs could also be more clever and only do this dance when the name really does span pages.. it's very rare. :/). - z -- 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
