SMB3 CLIENT FIXES LAND AS RC2 SWEEP CONTINUES

Linux 7.2-rc2 pushed a massive SMB3 client update overnight that closes a critical buffer overflow in ioctl_query_info and fixes broken symlink handling on mounted filesystems.

The SMB3 client stack [1] got the heaviest attention in today's merge window, addressing eleven separate issues including a bounds check failure in DFS referral processing that could have caused heap corruption, plus fixes for nlink reporting on fstat calls and atime corruption on read completion. On the graphics side [2], AMD's GPU driver continues leading the load with AMDGPU and AMDXDNA fixes dominating the drm pull, while core adjustments in the fb-helper sync logic and drm_exec labeling shore up stability across the display pipeline. The ATA layer [3] pulled in security-focused fixes that prevent locked drives from being dropped on resume, a critical piece for enterprise environments where encrypted storage stays locked across power cycles. Audit subsystem [4] closed potential integer overflows in hex logging and data races on the backlog queue that could corrupt security logs under load. Regulator core [5] patched device loading issues and fixed voltage selection logic for closely-spaced regulator targets.
