I noticed... lot of code using in_interrupt() to decide what to do is
making it to 5.10-stable at the moment (and I guess that means
vanilla, too).
I have recollection that that is not okay thing to do. Am I right?
Examples: 8abec36d1274bbd5ae8f36f3658b9abb3db56c31,
d68b29584c25dbacd01ed44a3e45abb35353f1de.
Best regards,
Pavel

Correct. These macros should not be added to new, non-core, kernel code.
There's an on-going effort to clear them already, as in:
- https://lkml.kernel.org/r/20201019100629.419020859@linutronix.de (merged)
- https://lkml.kernel.org/r/20201126132952.2287996-1-bigeasy@linutronix.de (merged)
- https://lkml.kernel.org/r/20210118100955.1761652-1-a.darwish@linutronix.de (to be merged)

That's sad.
Maybe it would be wise to let a bot scan lore regularly, and send an
automatic notification to authors whenever their patches reintroduce
these macros to non-core kernel code.
