      Drivers: scsi: remove __dev* attributes. · 6f039790
      Greg Kroah-Hartman 提交于
      CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
      markings need to be removed.
      
      This change removes the use of __devinit, __devexit_p, __devinitdata,
      __devinitconst, and __devexit from these drivers.
      
      Based on patches originally written by Bill Pemberton, but redone by me
      in order to handle some of the coding style issues better, by hand.

      megaraid: fix BUG_ON() from incorrect use of delayed work · c1d390d8
      Xiaotian Feng 提交于
      megaraid use INIT_WORK to declare a hotplug_work, but cast the
      hotplug_work from work_struct to delayed_work and
      schedule_delayed_work on it.  This is very dangerous, as other part of
      delayed_work might be kernel memories allocated by others.
      
      With commit 8852aac2 ("workqueue: mod_delayed_work_on() shouldn't queue
      timer on 0 delay"), schedule_delayed_work() will check dwork->timer
      before queue_work even when @delay is 0, this causes megaraid code to
      hit the BUG_ON() in workqueue code.  Change megaraid code to use
      delayed work.

      [SCSI] megaraid_sas: Sanity check user supplied length before passing it to dma_alloc_coherent() · 98cb7e44
      Bjørn Mork 提交于
      The ioc->sgl[i].iov_len value is supplied by the ioctl caller, and can be
      zero in some cases.  Assume that's valid and continue without error.
      
      Fixes (multiple individual reports of the same problem for quite a while):
