gnn	dd583c889b	Change the module name for the I/O provider to "kernel" from ... "genunix" This will requires us to modify externally created DTrace scripts but makes logical sense for FreeBSD. Requested by: rpaulo MFC after: 2 weeks	2012-09-25 19:16:28 +00:00
gnn	786ac82553	Initial commit of an I/O provider for DTrace on FreeBSD. ... These probes are most useful when looking into the structures they provide, which are listed in io.d. For example: dtrace -n 'io:genunix::start { printf("%d\n", args[0]->bio_bcount); }' Note that the I/O systems in FreeBSD and Solaris/Illumos are sufficiently different that there is not a 1:1 mapping from scripts that work with one to the other.
