Thank you. I am basing my work on the branch you have
pushed.(or-6.9-bh-conversions)
https://git.kernel.org/pub/scm/linux/kernel/git/tj/wq.git/log/?h=for-6.9-bh-conversions

In the order of priority, I have started converting drivers/media/*,
drivers/dma/* followed by drivers/net/*
which constitutes the majority. Putting my plan out here so that the
work is not duplicated.
I will write back in a day and share the branch for review.

W.r.t the conversion, there are drivers which call
tasklet_[disable/enable](), which I suppose
can be ignored in the case of workqueues, I am not entirely sure if
this is the right approach.
Please correct me if I am wrong.


Thanks,
