I'm going to take this in (to top-of-tree), but
I'll be modifying it slightly (xfs_extlen_t is
not a struct, so I'll initialize with a simple 0).
It may well be that these variables never get used
without being set, but it's not at all clear from
a quick look so this is a simple fix.
Thanks for reporting the warning.
