The purpose of O_DIRECT is to move the cache handling from kernel space to userspace. Does ietd not implement a cache in user space?
Almost certainly not - that would somewhat negate the idea of using direct IO.
Not at all. Direct IO is used to avoid double buffering (which in some cases can result in significant slow down) and give application full control over when it flushes data to disk. It does not mean application should refrain from caching. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
