New Revision: 250461
URL: http://svnweb.freebsd.org/changeset/base/250461

Log:
  MFC r249951
  
  According to devctl(4), clients must read events whole; they may not piece them
  together from multiple reads().  It's as if /dev/devctl is a datagram device
  instead of a stream device.  However, devd's internal buffer was too small
  (1025 bytes) to read an entire ereport.fs.zfs.checksum event (variable, up to
  ~1300 bytes).  This commit enlarges the buffer to 8k.
