Summary
io_uring/rw: split io_read() into a helper
Details

In the Linux kernel, the following vulnerability has been resolved:

IORINGOPREAD did not correctly consume the provided buffer list when read i/o returned < 0 (except for -EAGAIN and -EIOCBQUEUED return). This can lead to a potential use-after-free when the completion via iorwdone runs at separate context.
