[PATCH nbdkit v3 0/2] cache: Implement cache-max-size and method of reclaiming space from the cache.
Patch 1 is the same as last time, except for a minor comment fix.
Patch 2 should address everything that Eric mentioned in his review,
and has been retested.

[PATCH nbdkit v4 0/2] cache: Implement cache-max-size and method of
v3 was broken by a bad rebase, so let's forget about that one.
Compared to v2:
- Patch 1 is the same except for a minor comment change.
- Patch 2 splits the reclaim code into a separate file
(filters/cache/reclaim.c)
- Addressed Eric's comments from his review of v2.
- Retested on Linux and FreeBSD.

v5:
- Now we set the block size at run time.
I'd like to say that I was able to test this change, but
unfortunately I couldn't find any easy way to create a filesystem
on x86-64 with a block size > 4K. Ext4 doesn't support it at all,
and XFS doesn't support block size > page size (and I

[PATCH nbdkit v2 0/4] cache: Implement cache-max-size etc.
These are essentially identical to what was previously posted as
patches 6/9 through 9/9 here:
https://www.redhat.com/archives/libguestfs/2018-December/msg00145.html
except that it has been rebased onto the current git master and
retested thoroughly.

[PATCH nbdkit 0/9] cache: Implement cache-max-size and method of reclaiming space from the cache.
This patch series enhances the cache filter in a few ways, primarily
adding a "cache-on-read" feature (similar to qemu's copyonread); and
adding the ability to limit the cache size and the antecedent of that
which is having a method to reclaim cache blocks.
As the cache is stored as a sparse temporary file, reclaiming cache
blocks simply means punching holes in the temporary file.
