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.
