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.
