Take a look at the for-loop in xfs_da_grow_inode_int:
======
for(){
nmap = min(XFS_BMAP_MAX_NMAP, count);
...
error = xfs_bmapi_write(...,&mapp[mapi], &nmap);//(..., $1, $2)
...
mapi += nmap;
}
=====
where $1 stands for the start address of the array,
while $2 is used to indicate the size of the array.
The array $1 will advance by $nmap in each iteration after
the allocation of extents.
But the size $2 still remains unchanged, which is determined by
min(XFS_BMAP_MAX_NMAP, count).
It seems that it has forgotten to trim the mapp array after each
iteration, so change it.
