+### BREAKING CHANGES
+
+* 1. 删除 LOS_CirBufLock()，LOS_CirBufUnlock()内核对外接口
+2. LOS_CirBufWrite()，LOS_CirBufRead()由原先内部不进行上/解锁操作，变为默认已包含上/解锁操作。
+* 新增支持API:
+
+LOS_LmsCheckPoolAdd使能检测指定内存池
+LOS_LmsCheckPoolDel不检测指定内存池
+LOS_LmsAddrProtect为指定内存段上锁，不允许访问
+LOS_LmsAddrDisableProtect去能指定内存段的访问保护
+* 1.新增一系列perf的对外API，位于los_perf.h中.
+    LOS_PerfInit配置采样数据缓冲区
+    LOS_PerfStart开启Perf采样
+    LOS_PerfStop停止Perf采样
+    LOS_PerfConfig配置Perf采样事件
+    LOS_PerfDataRead读取采样数据
+    LOS_PerfNotifyHookReg 注册采样数据缓冲区的钩子函数
+    LOS_PerfFlushHookReg 注册缓冲区刷cache的钩子
+
+2. 用户态新增perf命令
+【Usage】:
+./perf [start] /[start id] Start perf.
+./perf [stop] Stop perf.
+./perf [read nBytes] Read nBytes raw data from perf buffer and print out.
+./perf [list] List events to be used in -e.
+./perf [stat] or [record] <option> <command>
+         -e, event selector. use './perf list' to list available events.
+         -p, event period.
+         -o, perf data output filename.
+         -t, taskId filter(whiltelist), if not set perf will sample all tasks.
+         -s, type of data to sample defined in PerfSampleType los_perf.h.
+         -P, processId filter(whiltelist), if not set perf will sample all processes.
+         -d, whether to prescaler (once every 64 counts), which only take effect on cpu cycle hardware event.
