Simplify Linux ftrace processing with Go.
package main
import (
"fmt"
"github.com/kofemann/linux_ftrace"
"os"
"os/signal"
)
func main() {
eventTrace := ftrace.NewEventTrace("sunrpc/xprt_transmit")
eventTrace.Enable()
c := eventTrace.EventSource()
signalChan := make(chan os.Signal, 1)
signal.Notify(signalChan, os.Interrupt)
loop:
for {
select {
case l, ok := <-c:
fmt.Println(l.String())
if !ok {
break loop
}
case <-signalChan:
fmt.Println("\nInterrupted...")
eventTrace.Disable()
}
}
}linux_ftrace uses the linux kernel model of using git not only a source repository, but also as a way to track contributions and copyrights.
Each submitted patch must have a "Signed-off-by" line. Patches without this line will not be accepted.
The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below:
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
then you just add a line saying ( git commit -s )
