History
Kirk McKusick 0cb652d925 Have to use bread() rather than UFS_BALLOC() when obtaining a 
previously allocated block as the previous use of the block may
have fallen out of the cache. Failure to reread its contents cause
zeroed results to be written instead of the proper contents.
Conversely, when the block is going to be entirely filled in, it
is not necessary reread the old contents.
