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.
