Hi all, I have three parameterized classes, named mq, mq_gsk and apache. The mq class always calls the mq_gsk class, but the apache class should only call the mq_gsk class when the mq class is not used in a hosts'' node definition Here is my configuration class mq ( $gsk_version = undef ) { require mq::params < ..... > cla...

This patch should fix the bug reported in https://lkml.org/lkml/2014/9/11/249. We have to initialize at least the atomic_flags and the cmd_flags when allocating storage for the requests. Otherwise blk_mq_timeout_check() might dereference uninitialized pointers when racing with the creation of a request. Also move the reset of cmd_flags for the initializing code to the point where a request is freed. So we will never end up with pending flush request indicators that might trigger dereferences of in...

Hi all, I''m having issues with Unicorn and connecting to RabbitMQ using the tmm1-amqp gem. I''ve tried lots of approaches.

(https://github.com/danielsdeleo/qusion) I''ve made a simple mod to Qusion for it to monkey patch unicorn...
