pipes get stated all thet time and this avoidably contributed to contention. The pipe lock is only held to accomodate MAC and to check the type. Since normally there is no probe for pipe stat depessimize this by having the flag. The pipe_state field gets modified with locks held all the time and it's not feasible to convert them to use atomic store. Move the type flag away to a separate variable as a simple cleanup and to provide stable field to read. Use short for both fields to avoid growing the struct. While here short-circuit MAC for pipe_poll as well. |
