  "message": "fs: Handle multiply claimed blocks more gracefully with mmb\n\nWhen a metadata block is referenced by multiple inodes and tracked by\nmetadata bh infrastructure (which is forbidden and generally indicates\nfilesystem corruption), it can happen that mmb_mark_buffer_dirty() is\ncalled for two different mmb structures in parallel. This can lead to a\ncorruption of mmb linked list. Handle that situation gracefully (at\nleast from mmb POV) by serializing on setting bh-\u003eb_mmb.\n\nReported-by: Ruikai Peng \u003cruikai@pwno.io\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nLink: https://patch.msgid.link/20260423090311.10955-2-jack@suse.cz\nSigned-off-by: Christian Brauner \u003cbrauner@kernel.org\u003e\n",
