[PATCH 12/33] xfs: move struct xfs_da_args to xfs_types.h

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

 



To allow passing a struct xfs_da_args to the high-level attr helpers
it needs to be easily includable by files like xfs_xattr.c.  Move the
struct definition to xfs_types.h to allow for that.
