In file ext4fs.c funtion ext4fs_read_file() compares an
unsigned expression with < 0 like below
lbaint_t blknr;
blknr = read_allocated_block(&(node->inode), i);
if (blknr < 0)
return -1;
blknr is of type ulong/uint64_t. read_allocated_block() returns
long int. So comparing blknr with < 0 will always be false. Instead
declare blknr as long int.
