Exposing "DIRECT" to userspace now might confuse users into expecting O_DIRECT behavior. I say this as an easily-confused user. In the future, perhaps O_DIRECT behavior can become per-splice (instead of just per-open) and can save SPLICE_F_DIRECT for that. > - We might want different flags for file-to-file splicing and acceleration > - We might want flags to require or forbid acceleration > - We might want to provide all these flags to sendfile, too Another syscall? I prefer not. Better to just maintain the sendfile API as-is for compatibility reasons and nudge users towards splice. > Thoughts? Objections? I'll try to test/comment more in a week or two (not much time for computing until then). -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
