+Subject: [PATCH] Unused iocbs in a batch should not be accounted as active.
+
+Since commit 080d676de095 ("aio: allocate kiocbs in batches") iocbs are
+allocated in a batch during processing of first iocbs.  All iocbs in a
+batch are automatically added to ctx->active_reqs list and accounted in
+ctx->reqs_active.
+
+If one (not the last one) of iocbs submitted by an user fails, further
+iocbs are not processed, but they are still present in ctx->active_reqs
+and accounted in ctx->reqs_active.  This causes process to stuck in a D
+state in wait_for_all_aios() on exit since ctx->reqs_active will never
+go down to zero.  Furthermore since kiocb_batch_free() frees iocb
+without removing it from active_reqs list the list become corrupted
+which may cause oops.
+
+Fix this by removing iocb from ctx->active_reqs and updating
+ctx->reqs_active in kiocb_batch_free().
