Did you hit this issue after you upgrade kernel from lower one to 5.0?
No, it was ok. Works perfectly.
Why there are dirty data/node in readonly filesystem?
No idea. It's fresh boot up.
Could you try below commands to make sure where it actually crash?
gdb f2fs.ko
l *(f2fs_balance_fs_bg+0x26c/0x2a8)
l *(f2fs_build_free_nids+0x394/0x510)
Ok, that will take a while. I'll need to revert back to pre-5.0 and
install gdb first and try to debug it.
Oh, btw, there's no "f2fs.ko" ... f2fs is compiled as built-in instead
of a module.
you could also try using below script in kernel dir.
./scripts/faddr2line <vmlinux path> f2fs_balance_fs_bg+0x26c
./scripts/faddr2line <vmlinux path> f2fs_build_free_nids+0x394
My best.,
Jeff
