We can just cleanup the code by calculating the #refs earlier, so we can just inline what remains of record_subpages().
Calculate the number of references/pages ahead of times, and record them only once all our tests passed.
I'm seeing failures in kselftest-mm in -next on at least Raspberry Pi 4 and Orion O6 which bisect to this patch. I'm seeing a NULL pointer dereference during the GUP test (which isn't actually doing anything as I'm just using a standard defconfig rather than one with the mm fragment):
On which -next label are you on? next-20250908 should no longer have that commit.
