There are there are three extents counters per inode, one for each of the forks. Two are in the legacy icdinode and one is directly in struct xfs_inode. Switch to a single counter in the xfs_ifork structure where it uses up padding at the end of the structure. This simplifies various bits of code that just wants the number of extents counter and can now directly dereference it.
