I have got the answer from a expert in the company:
free pages in ZONE_DMA32 should exclude free_cma and lowmem_reserve[ZONE_NORMAL]

157208kB - 73684kB - 20049*4KB = 3328 KB < 3356kB(min watermark)

There will be no fallback in this case.

Reasons:
  • Low length (0.5):
  • Has code block (-0.5):
  • Self-answer (0.5):
  • Low reputation (1):
