virtio: console: Return -EFAULT on copy_xx_user errors, allow larger writes
Hey Rusty,
These updated patches in the series return -EFAULT on copy_xx_user
errors and also move the copy_from_user into fops_write() instead of it
being in send_buf. This enables send_buf to just read from kernel
buffers, making it simpler.
This also allows write()s to write more to the host in one go,
removingthe 4k limitation. I do limit the writes to 32k at once to not
put too much
