      [SCSI] megaraid_sas: Sanity check user supplied length before passing it to dma_alloc_coherent() · 98cb7e44
      由 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):

      [SCSI] remove flush_scheduled_work() usages · a684b8da
      由 Tejun Heo 提交于 
      Simple conversions to drop flush_scheduled_work() usages in
drivers/scsi.  More involved ones will be done in separate patches.

* NCR5380, megaraid_sas: cancel_delayed_work() +
  flush_scheduled_work() -> cancel_delayed_work_sync().

* mpt2sas_scsih: drop unnecessary flush_scheduled_work().

* arcmsr_hba, ipr, pmcraid: flush the used work explicitly instead of
  using flush_scheduled_work().
