Subject: [SCSI] mpt2sas: _scsih_smart_predicted_fault uses GFP_KERNEL in interrupt context
Date: Sun, 31 Jul 2011 19:29:09 +1000 [thread overview]
Message-ID: <20110731192909.16bb341e@kryten> (raw)
_scsih_smart_predicted_fault is called in an interrupt and therefore
must allocate memory using GFP_ATOMIC.
