Hi!
One or more kernel tests failed:
ppc64le: ??? LTPHi, I see max_map_count failed on ppc64le: https://artifacts.cki-project.org/pipelines/385189/logs/ppc64le_host_2_LTP_m...
That's strange, we do attempt to map 65536 mappings but we do not touch them, so these shouldn't be faulted in, so there is no real reason why mmap() in the child process should stop prematurely at 65532.
I guess that we cannot do much here, unless it's reproducible, because there is not much information there.
max_map_count.c:205: FAIL: 64882 map entries in total, but expected 65536 entries
I can reproduce it by running it in loop for couple hours. Though no idea why we started seeing it only in 5.4.13 rc kernels, as there doesn't seem to be any significant mm changes.
I'll try some older kernels.
