When venti(8) reads a data block into the cache, it can initiate a
readahead which goes beyond the last allocated block in the
data arena. This does no direct harm, but results in a rather
alarming error message "clump has bad magic number=00000000", which
may cause unnecessary anxiety by suggesting that the venti store is
corrupted.
Here's a correction:
