Hi Jan,

We have reproduced the crash with CONFIG_BLK_DEV_WRITE_MOUNTED disabled to obtain the same crash log. The new crash log, along with C and Syzlang reproducers are provided below:

Syzlang reproducer: https://drive.google.com/file/d/1R9QDUP2r7MI4kYMiT_yn-tzm6NqmcEW-/view?usp=sharing

I’m not sure if this is sufficient to help locate the bug? If you need additional information, please let me know.

Thanks,
