  "message": "[PATCH] NUMA slab locking fixes: irq disabling from cahep-\u003espinlock to l3 lock\n\nEarlier, we had to disable on chip interrupts while taking the\ncachep-\u003espinlock because, at cache_grow, on every addition of a slab to a slab\ncache, we incremented colour_next which was protected by the cachep-\u003espinlock,\nand cache_grow could occur at interrupt context.  Since, now we protect the\nper-node colour_next with the node\u0027s list_lock, we do not need to disable on\nchip interrupts while taking the per-cache spinlock, but we just need to\ndisable interrupts when taking the per-node kmem_list3 list_lock.\n\nSigned-off-by: Alok N Kataria \u003calokk@calsoftinc.com\u003e\nSigned-off-by: Ravikiran Thirumalai \u003ckiran@scalex86.org\u003e\nSigned-off-by: Shai Fultheim \u003cshai@scalex86.org\u003e\nCc: Christoph Lameter \u003cchristoph@lameter.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
