From: Olaf Weber <olaf@xxxxxxx>
With the introduction of the xfs_nameops.normhash callout, all uses of the
hashname callout now occur in places where an xfs_name structure must be
explicitly created just to match the parameter passing convention of this
callout. Change the arguments to a const unsigned char * and int instead.
Signed-off-by: Olaf Weber <olaf@xxxxxxx>
[v2: pass a 3rd argument for sb_utf8version to hashname. --bpm]
