Description

For sles11 lustre expands s_mount_opts to unsigned long long:

ldiskfs/kernel_patches/patches/ext4-misc-sles11.patch:

"data mode %x\n",
bh, is_metadata, inode->i_mode,
test_opt(inode->i_sb, DATA_FLAGS));

test_opt(inode->i_sb, DATA_FLAGS) is unsigned long long now, so it should be printed as %Lx
