Thanks for report! I see this didn't get any reply. Can you still hit this
issue with 5.8? If yes, what workload do you run on the machine to trigger
this? Can you send contents of /proc/mounts please? Thanks!

Also, do you have CONFIG_READ_ONLY_THP_FOR_FS set?
hello,
# CONFIG_READ_ONLY_THP_FOR_FS is not set

hello!
no issue yet with 5.8:
Linux version 5.8.0.20200803 ([email protected]) (gcc (GCC) 10.2.0,
GNU ld version 2.33.1-slack15) #1 SMP Mon Aug 3 16:17:10 EAT 2020
it seems that the bug was triggered when i ran programs compiled
against gcc-9.3.0 under kernel build with gcc-10.1.0, but not sure if
that is the real problem. running the programs under the same compiler
doesn't exhibit the bug and since i rebuilt the programs with
gcc-10.1.0, i no longer hit the issue.
