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. # # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # <
