| | | | | * runtime/alloc.c (_stp_alloc_percpu): Refuses to allocate too much percpu memory.
* Adapt to linux-next commit changing __alloc_percpu API.Frank Ch. Eigler2009-03-081-22/+3
| | | | | After linux-next commit f2a8205c, it takes two parameters again, so we autoconf for it rather than use KERNEL_VERSION ifdefs.
* Use 'static' as much as possibleJosh Stone2009-01-281-8/+8
| | | | | | | | | | This change just inserts 'static' on runtime, tapset, and generated C functions and globals, so the compiler can do a better job of optimizing. My tests with small scripts show ~10% reduction in compile time and ~20% reduction in module size. Larger scripts may show less benefit, but I expect purely positive results.
