`logger` and `counter` params are used with

should be amenable to extending to e.g. globbing

librbd: trim header update not using AIO
The original trim header update code was using blocking IO to
update the header. After migrating to an asynchronous trim
which performs all work in librados callbacks, it exposed a
potential deadlock in the librados_test_stub when attempting
to do blocking IO within a librados callback. This commit
changes the header update to use AIO.

We left this off because it seemed the same as DONTNEED, but there is a
subtle distinction: DONTNEED means nobody will need it (and we probably
discard our cache), while NOREUSE means this client won't need it again
(and we should try to avoid polluting the cache from this IO only). At
least, that's the way we'r defining it. posix_fadvise says:
POSIX_FADV_NOREUSE
The specified data will be accessed only once.
POSIX_FADV_DONTNEED
The specified data will not be accessed in the near future.
