fs/xfs/linux-2.6/xfs_file.c: In function "xfs_file_readdir":
fs/xfs/linux-2.6/xfs_file.c:289: warning: passing argument 4 of
â(vp->v_bh.bh_first->bd_ops)->vop_readdirâ from incompatible pointer type
loff_t * for f_pos, vs xfs_off_t * which is what the interface
is defined to take.
typedef __kernel_loff_t loff_t;
typedef long long __kernel_loff_t;
typedef __s64 xfs_off_t;
So they are both signed 64 bit types on all platforms so the
compiler warning is spurious. Just add a cast to bhv_vop_readdir()?
