Atomic Spinlock
From RTwiki
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 |
| insomniac_spinlock | No geek slang |
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.
