It would be nice if coverage functionality can extract filenames in the source
code and supply the list of filenames as arguments for bisect operation.

Also, (unrelated but) it would be nice if we can have "make yes2modconfig"
target which converts CONFIG_FOO=y to CONFIG_FOO=m if FOO is tristate.
syzbot is testing kernel configs close to "make allyesconfig" but I want to
save kernel rebuild time by disabling unrelated functionality when manually
"debug printk()ing" kernels.
