      "message": "fs: scale mntget/mntput\n\nThe problem that this patch aims to fix is vfsmount refcounting scalability.\nWe need to take a reference on the vfsmount for every successful path lookup,\nwhich often go to the same mount point.\n\nThe fundamental difficulty is that a \"simple\" reference count can never be made\nscalable, because any time a reference is dropped, we must check whether that\nwas the last reference. To do that requires communication with all other CPUs\nthat may have taken a reference count.\n\nWe can make refcounts more scalable in a couple of ways, involving keeping\ndistributed counters, and checking for the global-zero condition less\nfrequently.\n\n- check the global sum once every interval (this will delay zero detection\n  for some interval, so it\u0027s probably a showstopper for vfsmounts).\n\n- keep a local count and only taking the global sum when local reaches 0 (this\n  is difficult for vfsmounts, because we can\u0027t hold preempt off for the life of\n  a reference, so a counter would need to be per-thread or tied strongly to a\n  particular CPU which requires more locking).\n\n- keep a local difference of increments and decrements, which allows us to sum\n  the total difference and hence find the refcount when summing all CPUs. Then,\n  keep a single integer \"long\" refcount for slow and long lasting references,\n  and only take the global sum of local counters when the long refcount is 0.\n\nThis last scheme is what I implemented here. Attached mounts and process root\nand working directory references are \"long\" references, and everything else is\na short reference.\n\nThis allows scalable vfsmount references during path walking over mounted\nsubtrees and unattached (lazy umounted) mounts with processes still running\nin them.\n\nThis results in one fewer atomic op in the fastpath: mntget is now just a\nper-CPU inc, rather than an atomic inc; and mntput just requires a spinlock\nand non-atomic decrement in the common case. However code is otherwise bigger\nand heavier, so single threaded performance is basically a wash.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n"
