Since io_uring, this isn't the case for most IO on Linux anymore.
- chrismorgan 7y agoI’m not terribly familiar with io_uring, and haven’t used it myself yet, but does it not still require a syscall to drive things, even though the buffers are shared? Brief investigation suggests the need for that might go away in the future? But all this io_uring stuff seems fairly immature yet and not widely used, though still definitely of interest.
