[PATCH v1 02/19] xfsprog: Replace attribute parameters with struct xfs_name

Allison Collins
2019-08-09T21:38:18Z

This patch replaces the attribute name, length and flags parameters with a
single struct xfs_name parameter. This helps to clean up the numbers of
parameters being passed around and pre-simplifies the code some.
