I searched the archives and found a thread from over a year ago
talking about adding support to dd for O_DIRECT, but it is not
documented in the man pages.
It's in coreutils 5.93 dd. Try, e.g., "dd iflag=direct". It's
not documented with the phrase "O_DIRECT", though, which is possibly
why you missed it.
does dd use aio so as to keep the IO pipelined, since a blocking
read/write would only be able to access one file/disk at a time?
Nope. Might be nice to add, I suppose.
