From edfaa7c36574f1bf09c65ad602412db9da5f96bf Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Mon, 21 May 2007 22:08:01 +0200 Subject: Driver core: convert block from raw kobjects to core devices This moves the block devices to /sys/class/block. It will create a flat list of all block devices, with the disks and partitions in one directory. For compatibility /sys/block is created and contains symlinks to the disks. /sys/class/block |-- sda -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda |-- sda1 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda1 |-- sda10 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda10 |-- sda5 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda5 |-- sda6 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda6 |-- sda7 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda7 |-- sda8 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda8 |-- sda9 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda9 `-- sr0 -> ../../devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr0 /sys/block/ |-- sda -> ../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda `-- sr0 -> ../devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr0 Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman --- drivers/block/aoe/aoeblk.c | 51 +++++++++++++++++++++++----------------------- 1 file changed, 25 insertions(+), 26 deletions(-) (limited to 'drivers/block/aoe') diff --git a/drivers/block/aoe/aoeblk.c b/drivers/block/aoe/aoeblk.c index ad00b3d9471..826d12381e2 100644 --- a/drivers/block/aoe/aoeblk.c +++ b/drivers/block/aoe/aoeblk.c @@ -15,8 +15,10 @@ static struct kmem_cache *buf_pool_cache; -static ssize_t aoedisk_show_state(struct gendisk * disk, char *page) +static ssize_t aoedisk_show_state(struct device *dev, + struct device_attribute *attr, char *page) { + struct gendisk *disk = dev_to_disk(dev); struct aoedev *d = disk->private_data; return snprintf(page, PAGE_SIZE, @@ -26,50 +28,47 @@ static ssize_t aoedisk_show_state(struct gendisk * disk, char *page) (d->nopen && !(d->flags & DEVFL_UP)) ?
