SubjectRe: [syzbot] KASAN: stack-out-of-bounds Read in iov_iter_revert
From
Hello,

syzbot has tested the proposed patch and the reproducer did not trigger any issue:

Reported-and-tested-by: syzbot+9671693590ef5aad8953@syzkaller.appspotmail.com

Tested on:

commit: bff2c168 io_uring: don't retry with truncated iter
git tree: https://github.com/isilence/linux.git truncate
kernel config: https://syzkaller.appspot.com/x/.config?x=730106bfb5bf8ace
dashboard link: https://syzkaller.appspot.com/bug?extid=9671693590ef5aad8953
compiler: Debian clang version 11.0.1-2, GNU ld (GNU Binutils for Debian) 2.35.1

Note: testing is done by a robot and is best-effort only.
