The +advantage of using completions is clear intent of the code but also more +efficient code as both threads can continue until the result is actually +needed. + +Completions are built on top of the generic event infrastructure in Linux, +with the event reduced to a simple flag appropriately called "done" in +struct completion, that tells the waiting threads of execution if they +can continue safely. + +As completions are scheduling related the code is found in +kernel/sched/completion.c - for details on completion design and +implementation see completions-design.txt + + +Usage: +------ + +There are three parts to the using completions, the initialization of the +struct completion, the waiting part through a call to one of the variants of +wait_for_completion() and the signaling side through a call to complete(), +or complete_all(). Further there are some helper functions for checking the +state of completions. + +To use completions one needs to include <linux/completion.h> and +create a variable of type struct completion. The structure used for +handling of completions is: + + struct completion { + unsigned int done; + wait_queue_head_t wait; + }; + +providing the wait queue to place tasks on for waiting and the flag for +indicating the state of affairs. + +Completions should be named to convey the intent of the waiter. A good +example is: + + wait_for_completion(&early_console_added); + + complete(&early_console_added); + +Good naming (as always) helps code readability. + + +Initializing completions: +------------------------- + +Initialization of dynamically allocated completions, often embedded in +other structures, is done with: + + void init_completion(&done); + +Initialization is accomplished by initializing the wait queue and setting +the default state to "not available", that is, "done" is set to 0. + +The re-initialization function, reinit_completion(), simply resets the +done element to "not available", thus again to 0, without touching the +wait queue. Calling init_completion() on the same completions object is +most likely a bug as it re-initializes the queue to an empty queue and +enqueued tasks could get "lost" - use reinit_completion() in that case. + +For static declaration and initialization, macros are available.
