Hello everyone, I'm maintaining a kernel for Pixel 7 android devices running the 5.10 kernel. After merging the latest updates from f2fs stable for 5.10, users experience a kernel panic, which I believe is caused by the most recently pushed tag there.
I never personally experienced the panic, but I got two ramoops/pstore logs that look exactly the same since I pushed the kernel containing the latest f2fs stable commits. One panic happened while the user was browsing chrome, the other while watching YouTube. Both crashes look identical in the kernel log. Here's the snipped from the kernel log: [ 271.459684][ T9723] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 [ 271.459713][ T9723] Mem abort info: [ 271.459725][
