Sorry, a couple people complained that I didn't actually say what smatch was.
It's an static analysis type error checker. It finds different bugs
than sparse. It's more like the stanford checker or maybe Microsoft's
PREfix. It can find more complicated bugs than coccinelle but it
can't fix them automatically. One key selling point is how simple it
is to write checks.
The error messages look like this:
drivers/scsi/pcmcia/nsp_cs.c +1725 nsp_cs_config(19) info: ignoring
unreachable code.
The 1725 is the line number. nsp_cs_config(19) is the function and
line number within the function.
Most of the error messages are false positives honestly, but some are real.
regards,
dan carpenter
