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
