Cyclic Code?

[Adil Mujeeb <mujeeb.adil@xxxxxxxxx>]

Hi list,

i am new to XFS.

I was going through XFS code (2.4 based) for study purpose. Its old but assuming its bit simple as compare to latest one. Moreover the XFS code / design structure documents available on the internet is 2.4 based.

The following code snippet is not clear to me (seems cyclic):

---------

...

...

#define XFS_IFORK_NEXTENTS(ip,w)        xfs_ifork_nextents(ip,w)

...

xfs_ifork_nextents(xfs_inode_t *ip, int w)

{

        return XFS_IFORK_NEXTENTS(ip, w);

}

...

...

#define XFS_IFORK_NEXTENTS(ip,w)        XFS_CFORK_NEXTENTS(&ip->i_d, w)

...

#define XFS_CFORK_NEXTENTS(dcp,w)            xfs_cfork_nextents(dcp,w)

...

int 

xfs_cfork_nextents(xfs_dinode_core_t *dcp, int w)

{

        return XFS_CFORK_NEXTENTS(dcp, w);

}

----

Am i missing something? 

Thanks,

Adil
