svn commit: r319679 - head/usr.bin/truss

[John Baldwin]

Author: jhb

New Revision: 319679
URL: https://svnweb.freebsd.org/changeset/base/319679

Log:
  Decode arguments passed to extended attribute related system calls.
  
  The cmd argument passed to extattrctl() is not decoded as a string constant
  but is just printed in hex.  The value is filesystem-specific but in
  practice is only used with UFS1 filesystems.
