Hi Simon


Thank you for the point you mentioned which I missed while working on this
patch. 

However, after thinking on it, I am still not able to get any fix to this
except that we can possibly implement the Ira's solution here which is:

https://lore.kernel.org/outreachy/64154d438f0c8_28ae5229421@iweiny-mobl.notmuch/

Although we have to then deal with 40 lines of ifs.
