Subject: Allow index block to be Realloc during truncate.
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=1597c0a6a252dec9d7de8ea9d5c6bfb76d2b5175;p=LaFS.git

Allow index block to be Realloc during truncate.

And data blocks in realloc will have been destroyed in
erase_dblock, but there could legitimately be Realloc index blocks
still, so allow them to be handled.
