[REGRESSION] 6.13-rc1: Loading nvme module leads to mm/page_alloc.c:4727 __alloc_pages_noprof+0x321/0x330

[Simon Polack <spolack@mailbox.org>]

Hello,

i noticed a regression after upgrading from 6.12.1 to 6.13-rc1. The logs 
indicate a error in mm/page_alloc.c which is called from the nvme 
module. Other modules seem to be not producing that warning, therefore i 
have included nvme maintainers as well.

The issue is seen on a Dell Latitude 5340 Notebook which is runnning 
Fedora 41 using vanilla kernel and the system seems to be still 
perfectly working, aside from the call trace.

Please bare with me in case i forgot to include relevant recipients or 
deviate from the exact process, as this is my first reported issue.

Best,
Simon
