Subject: [PATCH 0/3] fs: ufs: Remove unused pointer

This is a cleanup throughout ufs regarding pointers that are set up, but no
longer used in the affected functions. The ubh_get_usb_(first|second|third)
macros found in the changesets all resolve to 

   static inline void *get_usb_offset(struct ufs_sb_private_info *uspi,
                                      unsigned int offset)
   {
           unsigned int index;

           index = offset >> uspi->s_fshift;
           offset &= ~uspi->s_fmask;
           return uspi->s_ubh.bh[index]->b_data + offset;
   }

and differ in the passed offset value. get_usb_offset() does not alter the
passed ufs_sb_private_info struct. Those calls can be thus removed safely
where the return value is not further used.

The series applies against v3.14-rc2 and is compile tested.

Christian Engelmayer (3):
  fs: ufs: Remove unused ufs_super_block_first pointer.
  fs: ufs: Remove unused ufs_super_block_second pointer.
  fs: ufs: Remove unused ufs_super_block_third pointer.
