Return to common.attr CVS log

Up to [Development] / xfs-cmds / xfstests

Fixed double function issue with the UDF merge.
Merge of xfs-cmds-melb:slinx:20266a by kenmcd.

  Changes the 2nd udf _filter_aces() function to _filter_aces_notypes() and combined it with the origional _filter_aces function. Added /ub($2, idlist[$2]); print; next} to origional _filter_aces() function.
