  Modified files:
    sys/sys              bio.h buf.h 
    sys/kern             vfs_bio.c vfs_cluster.c 
  Kernel support for HAMMER:
  * Add another type to the bio->bio_caller_info1 union
  * Add two new flags to getblk(), used by the cluster code.
    GETBLK_SZMATCH	- Tell getblk() to fail and return NULL if a
  			  pre-existing buffer's size does not match
  			  the requested size (this prevents getblk()
  			  from doing a potentially undesired bwrite()
    GETBLK_NOWAIT		- Tell getblk() to use a non-blocking lock.
  * pop_bio() now returns the previous BIO (or NULL if there is no previous
    BIO).  This allows HAMMER to chain bio_done()'s
  * Fix a bug in cluster_read().  The cluster code's read-ahead at the
    end could go past the caller-specified limit and force a block to
    the wrong block size.
