Current kernels have a call to trace_mm_vmscan_lru_shrink_inactive() in
evict_folios(), so this renaming broke the build.
Sorry, I did not enable CONFIG_LRU_GEN

evict_folios(), so this renaming broke the build.
From: cuibixuan
Add a new event to calculate the shrink_inactive_list()/shrink_active_list()
execution time.
Example of output:
kswapd0-103 [007] . 1098.353020:
mm_vmscan_lru_shrink_active_start: nid=0
kswapd0-103 [007] . 1098.353040:
mm_vmscan_lru_shrink_ac
