#     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.
#
