LeapIO inclusion category: feature bugzilla: https://atomgit.com/openeuler/kernel/issues/8463 ------------------------------------------ This change introduces RAID disk hide/show events to allow dynamic visibility control of RAID devices. It also updates the MSI-X vector count retrieval logic and unifies driver naming from LeapRaid to LeapRAID for consistency. In addition, fix an issue where the fw_log workqueue was not properly released during system shutdown, which could lead to resource leaks.
