      "message": "mempool: fix and document synchronization and memory barrier usage\n\nmempool_alloc/free() use undocumented smp_mb()\u0027s.  The code is slightly\nbroken and misleading.\n\nThe lockless part is in mempool_free().  It wants to determine whether the\nitem being freed needs to be returned to the pool or backing allocator\nwithout grabbing pool-\u003elock.  Two things need to be guaranteed for correct\noperation.\n\n1. pool-\u003ecurr_nr + #allocated should never dip below pool-\u003emin_nr.\n2. Waiters shouldn\u0027t be left dangling.\n\nFor #1, The only necessary condition is that curr_nr visible at free is\nfrom after the allocation of the element being freed (details in the\ncomment).  For most cases, this is true without any barrier but there can\nbe fringe cases where the allocated pointer is passed to the freeing task\nwithout going through memory barriers.  To cover this case, wmb is\nnecessary before returning from allocation and rmb is necessary before\nreading curr_nr.  IOW,\n\n\tALLOCATING TASK\t\t\tFREEING TASK\n\n\tupdate pool state after alloc;\n\twmb();\n\tpass pointer to freeing task;\n\t\t\t\t\tread pointer;\n\t\t\t\t\trmb();\n\t\t\t\t\tread pool state to free;\n\nThe current code doesn\u0027t have wmb after pool update during allocation and\nmay theoretically, on machines where unlock doesn\u0027t behave as full wmb,\nlead to pool depletion and deadlock.  smp_wmb() needs to be added after\nsuccessful allocation from reserved elements and smp_mb() in\nmempool_free() can be replaced with smp_rmb().\n\nFor #2, the waiter needs to add itself to waitqueue and then check the\nwait condition and the waker needs to update the wait condition and then\nwake up.  Because waitqueue operations always go through full spinlock\nsynchronization, there is no need for extra memory barriers.\n\nFurthermore, mempool_alloc() is already holding pool-\u003elock when it decides\nthat it needs to wait.  There is no reason to do unlock - add waitqueue -\ntest condition again.  It can simply add itself to waitqueue while holding\npool-\u003elock and then unlock and sleep.\n\nThis patch adds smp_wmb() after successful allocation from reserved pool,\nreplaces smp_mb() in mempool_free() with smp_rmb() and extend pool-\u003elock\nover waitqueue addition.  More importantly, it explains what memory\nbarriers do and how the lockless testing is correct.\n\n-v2: Oleg pointed out that unlock doesn\u0027t imply wmb.  Added explicit\n     smp_wmb() after successful allocation from reserved pool and\n     updated comments accordingly.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: \"Paul E.

So if allocation\nstill fails, then we can probably afford to hit the pool-\u003elock - and what\u0027s\nthe alternative?
