| |
This patchset extends kcov to allow collecting coverage from the USB subsystem and vhost workers. See the first patch description for details about the kcov extension. The other two patches apply this kcov extension to USB and vhost.
These patches have been used to enable coverage-guided USB fuzzing with syzkaller for the last few years, see the details here:
