Christophe JAILLET 706dc3b919 scsi: message: fusion: mptctl: Use dma_alloc_coherent() ... In [1], Christoph Hellwig has proposed to remove the wrappers in include/linux/pci-dma-compat.h. Some reasons why this API should be removed have been given by Julia Lawall in [2]. When memory is allocated in kbuf_alloc_2_sgl() GFP_KERNEL can be used because this function already uses the GFP_USER flag for some memory allocation and not spin_lock is taken in the between. When memory is allocated in mptctl_do_mpt_command() GFP_KERNEL can be used because this function already uses copy_from_user() and this function can sleep. When memory is allocated in mptctl_hp_hostinfo() GFP_KERNEL can be used because this function already uses mpt_config() and this function has an explicit might_sleep(). When memory is allocated in mptctl_hp_targetinfo() GFP_KERNEL can be used because this function already uses mpt_config() and this function has an explicit might_sleep().
