Thanks, I added this to mm.git. I suppressed the usual added-to-mm emails because soooo many cc's! I'd ask relevant maintainers to send in any acks and I'll paste them into the relevant changelogs.

More confusingly still, they did send one standalone patch for an Ethernet driver: https://lore.kernel.org/all/20241210-converge-secs-to-jiffies-v3-20-59479891e658@linux.microsoft.com/ And yet another Ethernet driver (drivers/net/ethernet/google/gve/) is converted in this series.

This is probably OK to have in this patch, but you should add additional description to mention that special case with a 0 delay. Allthough you should probably change it to schedule_work() instead of using a 0 delay. Christophe

This is a series that follows up on my previous series to introduce secs_to_jiffies() and convert a few initial users.[1] In the review for that series, Anna-Maria requested converting other users with Coccinelle. [2] This is part 1 that converts users of msecs_to_jiffies() that use the multiply pattern of either of: - msecs_to_jiffies(N*1000), or - msecs_to_jiffies(N*MSEC_PER_SEC) where N is a constant, to avoid the multiplication. The entire conversion is made with Coccinelle in the script added in patch 2. Some changes suggested by Coccinelle have been deferred to later parts that will address other possible variant patterns.
