Description: This patch adds the dynamic equivalent of Rusty Russell's static per-CPU data area. It inroduces a set of interfaces - kmalloc_percpu() and kfree_percpu() for alloc/free of per-cpu data and then provides a set of per_cpu_ptr() interfaces to access the data. The interfaces are just matching extensions of existing interfaces in the kernel. The main motivation behind this is that static per-CPU data area cannot be used in modules and in dynamically allocated data structures. Its potential uses are in per-cpu statistics counters used in drivers or "modulable" network/fs code. |
