Revision as of 14:18, 27 September 2009
The new 2.6.31-rc4-rt1 patch annotates spinlocks which can not be converted to sleeping "spinlocks" as atomic_spinlock_t. The name is not perfect and we are looking for a better one which avoids the atomic confusion and expresses the fact that this lock always spins and disables preemption as well.
Please add your suggestions to the list below.
| name | rationale |
|---|---|
| atomic_spinlock | the current name, confusing vs. the atomic* APIs |
| real_spinlock | self explaining, but sucks |
| hard_spinlock | close, but sucks more |
| preemption_disabling_never_sleeping_spinlock | way tooo long |
| vanilla_spinlock | self explaining...but don't know if it is any better. :) |
| pure_spinlock | sucks more than hard_spinlock? |
| indivisible_spinlock | sucks more than hard_spinlock? |
| nonrt_spinlock | inimicle to RT, better than evil_spinlock? |
| ondine_spinlock | not self explaining, a bit of mythology? |
| spinning_lock | same concept, easy identification |
| nuclear_spinlock | more indivisible than atomic |
| quark_spinlock | another two divisions smaller than the nucleus |
| insomniac_spinlock | No geek slang |
| sleepless_spinlock | |
| greedy_spinlock | |
| big_spinlock | |
| inconsiderate_spinlock | don't use it |
| busy_spinlock | |
| caffeinated_spinlock | too many espressos |
| topspinlock | tennis anyone? |
| slow_spinlock | because it slows other things down |
| busywait_spinlock | This name accurately describes its behavior and discourages people from using it (without deep thought). |
| rude_spinlock | |
| busywait_lock | Has same connotations as busywait_spinlock, but is more terse. Instead of trying to augment the 'spinlock' nomenclature, just abandon the 'spin' part of it and call it something else that describes what it does. |
| snooze_lock | Short, Simple, descriptive. Alternatively, snooze_spinlock, but that sounds goofy. |
| hamster_wheel_lock | Makes a hamster stay awake waiting for more food. Makes a thread stay awake waiting for more work. |
| livelock_t | It never rests, and is probably best left to experts (like touching a live wire) |
| thor_spinlock | If you use it you will get hit by Thor's Hammer :) |
| native_spinlock | |
| cpu_spinlock | Uses CPU 100% - Cannot be put to sleep |
| retarding_spinlock | Can retard other processes... |
| pure_spinlock | |
| spider_lock | |
| busy_lock | |
| active_spinlock | as opposed to sleeping_spinlock |
| hyperactive_spinlock | |
| radioactive_spinlock | to discourage it's use : ) |
| wake_lock | A lock that prevents sleep, term used for something similar on Android. |
| core_spinlock | (Added on behalf of Doug Niehaus who came up with that name) |
| nopreempt_spinlock | |
| spin_spinlock | |
| skid_lock | :-) |
| dread_lock | (Added on behalf of Peter Zijlstra and Jonathan Corbet from the RT mini-summit) |
If we pick one of the suggested names based on its accuracy and obviousness the inventor can expect free beer at a FOSS conference where ( tglx) happens to be there as well.
