Linus Torvalds 7e74e235bb gcc-9: don't warn about uninitialized btrfs extent_type variable ... The 'extent_type' variable does seem to be reliably initialized, but it's _very_ non-obvious, since there's a "goto next" case that jumps over the normal initialization. That will then always trigger the "start >= extent_end" test, which will end up never falling through to the use of that variable. But the code is certainly not obvious, and the compiler warning looks reasonable. Make 'extent_type' an int, and initialize it to an invalid negative value, which seems to be the common pattern in other places.
