Kernel Locking Techniques

Proper locking can be tough--real tough. Improper locking can result in random crashes and other oddities.
Poorly designed locking can result in code that is hard to read, performs poorly and makes your fellow kernel
developers cringe. In this article, I explain why kernel code requires locking, provide general rules for proper
kernel locking semantics and then outline the various locking primitives in the Linux kernel
