-### 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.
