mainline inclusion from mainline-v7.2-rc2 commit 462775c620197adaabc983ce847e5b9878ff4cb0 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/17314 CVE: CVE-2026-72031 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- The PNY CS900 1TB SSD (Phison PS3111-S11, DRAM-less) drops off the bus after entering Device-Initiated Slumber during idle. With the default med_power_with_dipm policy the link goes down (SStatus 1 SControl 300) and does not recover, forcing the filesystem read-only. Forcing max_performance keeps the link stable across prolonged idle. Add a NOLPM quirk so link power management is disabled for this drive specifically, leaving it intact for other devices on the host.
