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. Similarly ext4/dev.c does a similar comparison. Drop the redundant comparison.
