I use FreeBSD 10.3-STABLE r317936 with "old" /usr/lib/dtrace/ip.c and can't get DTrace to work for the function g_journal_read(). In the output of "dtrace -lv" I see 33379 fbt geom_journal g_journal_read entry Probe Description Attributes Identifier Names: Private Data Semantics: Private Dependency Class: Unknown Argument Attributes Identifier Names: Private Data Semantics: Private Dependency Class: ISA Argument Types args[0]: struct g_journal_softc * args[1]: off_t args[2]: off_t args[3]: struct bio * but the sourcefile g_journal.c gives static void g_journal_read(struct g_journal_softc *sc, struct bio *pbp, off_t ostart, off_t oend) So args[0] and args[2] matches in type, but args[1] and args[3] does not. This problem did not exist in FreeBSD V8, dtrace -lv gives correct 31519 fbt geom_journal g_journal_read entry Probe Description Attributes Identifier Names: Private Data Semantics: Private Dependency Class: Unknown Argument Attributes Identifier Names: Private Data Semantics: Private Dependency Class: ISA Argument Types args[0]: struct g_journal_softc * args[1]: struct bio * args[2]: off_t args[3]: off_t Please can somebody show me how this can be fixed ? -- Andreas Longwitz
