  "message": "Unused iocbs in a batch should not be accounted as active.\n\nSince commit 080d676de095 (\"aio: allocate kiocbs in batches\") iocbs are\nallocated in a batch during processing of first iocbs.  All iocbs in a\nbatch are automatically added to ctx-\u003eactive_reqs list and accounted in\nctx-\u003ereqs_active.\n\nIf one (not the last one) of iocbs submitted by an user fails, further\niocbs are not processed, but they are still present in ctx-\u003eactive_reqs\nand accounted in ctx-\u003ereqs_active.  This causes process to stuck in a D\nstate in wait_for_all_aios() on exit since ctx-\u003ereqs_active will never\ngo down to zero.  Furthermore since kiocb_batch_free() frees iocb\nwithout removing it from active_reqs list the list become corrupted\nwhich may cause oops.\n\nFix this by removing iocb from ctx-\u003eactive_reqs and updating\nctx-\u003ereqs_active in kiocb_batch_free().\n\nSigned-off-by: Gleb Natapov \u003cgleb@redhat.com\u003e\nReviewed-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nCc: stable@kernel.org   # 3.2\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
