From: Arnaldo Carvalho de Melo <a...@redhat.com> Now anything that uses STRARRAY_FLAGS, like the 'fsmount' syscall will support mapping or-ed strings back to a value that can be used in a filter.
In some cases, where STRARRAY_FLAGS isn't used but instead the scnprintf is a special one because of specific needs, like for mmap, then one has to set the ->pars to the strarray. See the next cset.
