  "message": "[PATCH] adapt page_lock_anon_vma() to PREEMPT_RCU\n\npage_lock_anon_vma() uses spin_lock() to block RCU.  This doesn\u0027t work with\nPREEMPT_RCU, we have to do rcu_read_lock() explicitely.  Otherwise, it is\ntheoretically possible that slab returns anon_vma\u0027s memory to the system\nbefore we do spin_unlock(\u0026anon_vma-\u003elock).\n\n[ Hugh points out that this only matters for PREEMPT_RCU, which isn\u0027t merged\n  yet, and may never be.  Regardless, this patch is conceptually the\n  right thing to do, even if it doesn\u0027t matter at this point.  - Linus ]\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Paul McKenney \u003cpaulmck@linux.vnet.ibm.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Christoph Lameter \u003cclameter@engr.sgi.com\u003e\nAcked-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
