Hi Jan,

Thank you very much for the incredibly detailed review and the design
insights!

I completely agree with your suggestion. Rushing too many fixes for
complex, concurrent race conditions into a single patch makes the
code harder to review and risks introducing subtle regressions.

Let's go ahead with the simple and straightforward v1 patch (which
has your Reviewed-by) to fix the original syzbot crash for now.

I will take your excellent suggestion to use fsdata for state
communication between write_begin and write_end, and I will work on
formulating a separate, cleaner patch series in the future to
address the remaining concurrent locking races you mentioned.

I will withdraw this v4 thread for now.

Thanks again for your guidance!

Best regards,
Aditya Prakash Srivastava
