  "message": "fs: fs_struct use seqlock\n\nUse a seqlock in the fs_struct to enable us to take an atomic copy of the\ncomplete cwd and root paths. Use this in the RCU lookup path to avoid a\nthread-shared spinlock in RCU lookup operations.\n\nMulti-threaded apps may now perform path lookups with scalability matching\nmulti-process apps. Operations such as stat(2) become very scalable for\nmulti-threaded workload.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n",
