[PATCH 1/2] xfsprogs: Pass xattr name and value length explicitly to xfs_attr_leaf_newentsize

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

 



This commit changes xfs_attr_leaf_newentsize() to explicitly accept name and
value length instead of a pointer to struct xfs_da_args. The next commit will
need to invoke xfs_attr_leaf_newentsize() from functions that do not have
a struct xfs_da_args to pass in.
