Subject: [PATCH v3 0/4] Block layer patches for kernel v5.8
Date: Mon, 18 May 2020 21:07:33 -0700	[thread overview]
Message-ID: <20200519040737.4531-1-bvanassche@acm.org> (raw)

Hi Jens,

The patches in this series are what I came up with as the result of
analyzing Alexander Potapenko's report about reading from null_blk.
Please consider these patches for kernel v5.8.

Thanks,

Bart.

Changes compared to v2:
- In patch 4/4, use __rq_for_each_bio() (Ming).

Changes compared to v1:
- Adjusted the comments added by patch "Document the bio_vec properties" as
  requested by Christoph.
- Left out the patch "Fix zero_fill_bio()" since it is not necessary.
- Moved zero_fill_bvec() from patch "Fix zero_fill_bio()" into patch
  "null_blk: Zero-initialize read buffers in non-memory-backed mode".

Bart Van Assche (4):
  block: Fix type of first compat_put_{,u}long() argument
  bio.h: Declare the arguments of the bio iteration functions const
  block: Document the bio_vec properties
  null_blk: Zero-initialize read buffers in non-memory-backed mode
