  "message": "fs: introduce a per-cpu last_ino allocator\n\nnew_inode() dirties a contended cache line to get increasing\ninode numbers. This limits performance on workloads that cause\nsignificant parallel inode allocation.\n\nSolve this problem by using a per_cpu variable fed by the shared\nlast_ino in batches of 1024 allocations.  This reduces contention on\nthe shared last_ino, and give same spreading ino numbers than before\n(i.e. same wraparound after 2^32 allocations).\n\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n",
