I'm attending a SNIA meeting today to discuss a (cross-OS) data
integrity aware API. We'll see what comes out of that.
With the Linux hat on I'm still mainly interested in pursuing the
sys_dio interface Joel and I proposed last year. We have good experience
with that I/O model and it suits applications that want to interact with
the protection information well. libaio is also on my list.
But obviously any help and input is appreciated...
I guess you are referring to the interface described here
http://www.spinics.net/lists/linux-mm/msg14512.html
Hmm, direct IO would mean we could not use the page cache. As we are
using it, that would not really suit us. libaio then might be another
option then.
What kind of help do you exactly need?
Thanks,
Bernd
