Kernel prepatch 7.3-rc7

The 7.3-rc7 kernel prepatch is out fortesting. According to Linus: "As always, I would have preferred to see a smallerrc, but it's not like anything in here looks like a reason to delaythe final release. So that's still set for next weekend unlesssomething new comes up."

One notable change that slipped into the mainline this week is the deprecationof the ext4 data=journal mode; it will be removed entirely at thebeginning of 2028.
