[PATCH v8 35/39] xfsprogs: Add helper function xfs_attr_node_removename_setup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch adds a new helper function xfs_attr_node_removename_setup.
This will help modularize xfs_attr_node_removename when we add delay
ready attributes later.
