The io_uring module has a vfs_io_uring:num_entries parameter
which by default is set to 128. The readv/writev requests are
queued inside smbd, but the number of outstanding io_uring
requests are set by io_uring_queue_init(vfs_io_uring:num_entries,...).
Can you try changing that value to see if the corruption point
moves ?
There is also a setting vfs_io_uring:sqpoll, currently set
to false. Try flipping that to true to see if it changes
the problem.
