Synopsis: 'Mbuf' instead of 'mbuf' in libmemstat(3)
State-Changed-From-To: open->patched

State-Changed-Why:
Slightly expanded version of patch applied (also renamed other references
to Mbuf) to HEAD, will MFC with re@'s permission. Thanks for the bug
report!
FYI: I've actually been considering committing a slightly larger example
that also retrieves the count from the mbuf_packet zone, since those are
also allocated mbufs. Something like the following:
struct memory_type_list *mtlp;
struct memory_type *mtp;
uint64_t mbuf_count, mbuf_packet_count;
mtlp = memstat_mtl_alloc();
if (mtlp == NULL)
err(-1, "memstat_mtl_alloc");
if (memstat_sysctl_uma(mtlp, 0) < 0)
err(-1, "memstat_sysctl_uma");
mtp = memstat_mtl_find(mtlp, ALLOCATOR_UMA, "mbuf");
if (mtp == NULL)
errx(-1, "memstat_mtl_find: mbuf not found");
mbuf_count = memstat_get_count(mtp);
mtp = memstat_mtl_find(mtlp, ALLOCATOR_UMA, "mbuf_packet");
if (mtp == NULL)
errx(-1, "memstat_mtl_find: mbuf_packet not found");
mbuf_packet_count = memstat_get_count(mtp);
memstat_mtl_free(mtlp);
printf("mbufs: %llu\n", (unsigned long long)(mbuf_count +
mbuf_packet_count));
