[PATCH 0/2] xfsprogs: metadump/restore fixes

[Dave Chinner]

Hi folks,

A couple of patches from trying to process a rather large, badly
broken filesystem from Arkadiusz Miskiewicz. The first patch
prevents a crash when zeroing unused regions of corrupt btree
blocks. The second patch makes mdrestore report progress correctly,
which is kind of important when you've got a 35+GB metadump image
being restored.

-Dave.
