I am pretty certain that Greg would have applied such a patch in an eye blink.
As you've said it, *probably*. But such a simple exit path as you're proposing
doesn't always exist. [...]
As I said it's case by case. I discussed your example (which was a deficient
patch
for multiple reasons) but we'd be wasting everyone's time by discussion
hypothethical situations.
Sure it was a deficient patch, but still better than what existed for a
year long in the kernel and which leaded to a reset of a system sometime
after a wireless remote connected device was turned off. And it showed
exactly where the problem existed. Maybe I should mention that almost a
year after I've posted that patch, people still stumbled over the
problem (and likely had the same hard time to find the reason for a
sudden reboot without any warning).
I just want to make clear that a brutforce slogan like BUG_ON is bad is
bad, especially as there are many people which just might repeat that
slogan without thinking about what they are repeating.
