Subject: [PATCH 0/4] Improve the configfs read and write iterators further

Hi Christoph,

This patch series addresses Linus' feedback on my most recent configfs patch,
adds unit tests for configfs and also includes one functional change that I
came up with while writing these unit tests. I will leave it to you to decide
whether to submit these patches for inclusion in kernel v5.14 or v5.15.

Thanks,

Bart.

Bart Van Assche (4):
  configfs: Rework the overflow check in fill_write_buffer()
  configfs: Fix writing at a non-zero offset
  kunit: Add support for suite initialization and cleanup
  configfs: Add unit tests
