kernel: md: fix mddev uaf while iterating all_mddevs list

A flaw was discovered in the Linux kernel’s MD multiple device subsystem during iteration over the allmddevs list in functions such as mdnotifyreboot and mdexit. The code used listforeachentrysafe, but released locks before completing reference counting, allowing concurrent deletion and freeing o...
