Straight from Linux Kernel Development 3rd Edition book...

In Linux kernel, there is no concept of thread. Linux implements all
threads as standard processes. Thread is just a process that shares
resources with other processes. There are no special data structures
to represent threads. Each thread has its own process descriptor and
appears to kernel as normal process - they just happen to shares
resource such as address space with other processes.
