[Libguestfs] [PATCH nbdkit v4 0/2] cache: Implement cache-max-size and method of

[Richard W.M. Jones]

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.
