Modified files:
sys/conf files
sys/geom geom.h geom_dev.c geom_int.h geom_io.c
geom_kern.c geom_subr.c
sys/geom/bde g_bde_lock.c g_bde_work.c
Added files:
sys/geom geom_stats.c geom_stats.h
Log:
Move the g_stat struct to its own .h file, we will export it to other code.
Insted of embedding a struct g_stat in consumers and providers, merely
include a pointer.
Remove a couple of <sys/time.h> includes now unneeded.
Add a special allocator for struct g_stat. This allocator will allocate
entire pages and hand out g_stat functions from there. The "id" field
indicates free/used status.
Add "/dev/geom.stats" device driver whic exports the pages from the
allocator to userland with mmap(2) in read-only mode.
This mmap(2) interface should be considered a non-public interface and
the functions in libgeom (not yet committed) should be used to access
the statistics data.
