Thanks for the suggestion -- it looks like we can make use of
this. For the curious, the cache advisory API is documented here:

http://www.lerctr.org:8458/en/man/html.7/vxfsio.7.html
http://www.lerctr.org:8458/en/ODM_FSadmin/fssag-9.html#MARKER-9-1

Note that unlike for posix_fadvise(), the docs for this functionality
explicitly state:

    Some advisories are currently maintained on a per-file, not a
    per-file-descriptor, basis. This means that only one set of
    advisories can be in effect for all accesses to the file. If two
    conflicting applications set different advisories, both use the
    last advisories that were set.
