  "message": "JFS is missing a memory barrier\n\nJFS is missing a memory barrier needed to close the critical section before\nclearing the lock bit. Use lock bitops for this.\n\nunlock_page() has a second barrier after clearing the lock, which is\nrequired because it checks whether the waitqueue is active without locks.\nSuch a barrier is not required here because the waitqueue spinlock is\nalways taken (something to think about if performance is an issue).\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Dave Kleikamp \u003cshaggy@linux.vnet.ibm.com\u003e\n",
