[PATCH 0/2] io_uring: mshot read fix for buffer size changes

[Dylan Yudaken <dyudaken@gmail.com>]

Hi,

This series fixes a bug (will send a liburing patch separately showing
it) where the used buffer size is clamped to the minimum of all the
previous buffers selected.

It also as part of this forces the multishot read API to set addr &
len to 0.
len should probably have some accounting post-processing if it has
meaning to set it to non-zero, but I think for a new API it is simpler
to overly-constrain it upfront?

addr is useful to force to zero as it will allow some more bits to be
used in `struct io_rw`, which is otherwise full.

Dylan Yudaken (2):
  io_uring: do not allow multishot read to set addr or len
  io_uring: do not clamp read length for multishot read
