Changes since v5: * Fix more locking mistakes; * Introduce get/put helpers; * Grabbed a reference when submitting an exec job with a binner slot. * Addressed misc comments. Changes since v4: * Used a kref on the binner bo instead of firstopen/lastclose; * Added a mutex to prevent race conditions; * Took care of enabling the OOM interrupt when we have a binner BO allocated. Changes since v3: * Split changes into more commits when possible; * Reworked binner bo alloc condition as discussed. Changes since v2: * Removed deprecated sentence about fristopen; * Added collected Reviewed-By tags. Changes since v1: * Squashed the two final patches into one.
