Subject: GFP_DMA in sd_revalidate_disk
Date: Fri, 23 Feb 2007 17:51:14 +0100	[thread overview]
Message-ID: <20070223165114.GA29468@strauss.suse.de> (raw)

Hello,

is GFP_DMA really needed in sd_revalidate_disk() in every circumstances?
That's the code:

    buffer = kmalloc(SD_BUF_SIZE, GFP_KERNEL | __GFP_DMA);
    if (!buffer) {
        printk(KERN_WARNING "(sd_revalidate_disk:) Memory allocation "
               "failure.\n");
        goto out;
    }

Or should could the check (sdp->host->unchecked_isa_dma ? __GFP_DMA : 0)
applied here, too?

Thanks!


Regards,
Bernhard
