From: Jihan LIN Currently, zcomp uses a preemptive per-CPU stream model where streams are allocated for each online CPUs and guarded by mutexes. The existing names zcomp_strm_{init, free}() are too generic to explicitly indicate they handle per-CPU streams. Rename them to zcomp_strm_{init, free}_percpu(). This helps distinguish them from future streams that may not be per-CPU based. No functional changes are intended.
