Hi, This work was originally suggested & started by Christoph Hellwig, when Zack Brown tried to add vectored support for AIO. These series of changes collapses all the vectored IO support into single file-operation method using aio_read/aio_write. Christoph & Zack, comments/suggestions ? If you are happy with the work, can you add your Sign-off or Ack ? Here is the summary: [PATCH 1/3] Vectorize aio_read/aio_write methods [PATCH 2/3] Remove readv/writev methods and use aio_read/aio_write instead. [PATCH 3/3] Zack's core aio changes to support vectored AIO. To Do/Issues: 1) Since aio_read/aio_write are vectorized now, need to modify nfs AIO+DIO and usb/gadget to handle vectors. Is it needed ? For now, it handles only single vector. Christoph, should I loop over all the vectors ? 2) AIO changes need careful review & could be cleaned up further. Zack, can you take a look at those ? 3) Ben's suggestion of kernel iovec to hold precomputed information (like total iolen) instead of computing every time.
