This patch creates a new key K_RELOAD. Once the __cmd_report() returns K_RELOAD, it would repeat the whole process, such as, read samples from data file, sort the data and display in the browser. v6: --- No change. v5: --- 1. Fix the 'make NO_SLANG=1' error. Define K_RELOAD in util/hist.h. 2. Skip setup_sorting() in repeat path if last key is K_RELOAD. v4: --- Need to quit in perf_evsel_menu__run if key is K_RELOAD. v3: --- No change. v2: --- This is a new patch created in v2.
