Bottomley; linux-scsi; linux-kernel; ldv-proj...@linuxtesting.org Subject: [PATCH v2] [SCSI] bfa: allocate memory with GFP_ATOMIC in spinlock context bfa_fcb_pbc_vport_create() is called only from bfa_fcs_pbc_vport_init(), that is called only from bfad_drv_start() with bfad_lock spinlock held. So the patch replaces GFP_KERNEL with GFP_ATOMIC to avoid sleeping in atomic spinlock context. Found by Linux Driver Verification project (linuxtesting.org).
