[Libguestfs] [nbdkit PATCH 0/2] More caching of initial setup

[Eric Blake]

When I added .can_FOO caching in 1.16, I missed the case that the sh
plugin itself was calling .can_flush twice in some situations (in
order to default .can_fua).  Then right after, I regressed it to call
.can_zero twice (in order to default .can_fast_zero).  I also missed
that .thread_model could use better caching, because at the time, I
did not add testsuite coverage.  Fix that now.

Eric Blake (2):
  sh, eval: Cache .can_zero and .can_flush
  server: Better caching of .thread_model
