    sys/kern             vfs_bio.c vfs_subr.c 
  Log:
  vfs_bio_awrite() was unconditionally locking a buffer without checking
  for races, potentially resulting in the wrong buffer, an invalid buffer,
  or a recently replaced buffer being written out.  Change the call semantics
  to require a locked buffer to be passed into the function rather then
  locking the buffer in the function.
