Return to 062 CVS log

Up to [Development] / xfs-cmds / xfstests

Add xfsdump support for the security extended attributes namespace.
Execute security attribute tests if $USE_ATTR_SECURE environment variable
is set to "yes" (security attribute tests disabled by default - "no").

#! /bin/sh
# XFS QA Test No. 062

# Exercises the getfattr/setfattr tools
# Derived from tests originally written by Andreas Gruenbacher for ext2
