      "title": "md raid: fix hang when stopping arrays with metadata through dm-raid",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmd raid: fix hang when stopping arrays with metadata through dm-raid\n\nWhen using device-mapper's dm-raid target, stopping a RAID array can cause\nthe system to hang under specific conditions.\n\nThis occurs when:\n\n- A dm-raid managed device tree is suspended from top to bottom\n   (the top-level RAID device is suspended first, followed by its\n    underlying metadata and data devices)\n\n- The top-level RAID device is then removed\n\nRemoving the top-level device triggers a hang in the following sequence:\nthe dm-raid destructor calls md_stop(), which tries to flush the\nwrite-intent bitmap by writing to the metadata sub-devices. However, these\ndevices are already suspended, making them unable to complete the write-intent\noperations and causing an indefinite block.\n\nFix:\n\n- Prevent bitmap flushing when md_stop() is called from dm-raid\ndestructor context\n  and avoid a quiescing/unquescing cycle which could also cause I/O\n\n- Still allow write-intent bitmap flushing when called from dm-raid\nsuspend context\n\nThis ensures that RAID array teardown can complete successfully even when the\nunderlying devices are in a suspended state.\n\nThis second patch uses md_is_rdwr() to distinguish between suspend and\ndestructor paths as elaborated on above.",
