When adding partition support to bcache, the name assignment was not updated, resulting in numbers jumping (bcache0, bcache16, bcache32...). Fix this by taking BCACHE_MINORS into account when assigning the disk name. BugLink: https://bugs.launchpad.net/bugs/1667078 Fixes: b8c0d91 (bcache: partition support: add 16 minors per bcacheN device) Cc: <stable@vger.kernel.org> # v4.10 Signed-off-by: Stefan Bader <stefan.bader@canonical.com> --- drivers/md/bcache/super.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/md/bcache/super.c b/drivers/md/bcache/super.c index 85e3f21..817e155 100644 --- a/drivers/md/bcache/super.c +++ b/drivers/md/bcache/super.c @@ -793,7 +793,8 @@ static int bcache_device_init(struct bcache_device *d, unsigned block_size, } set_capacity(d->disk, sectors); - snprintf(d->disk->disk_name, DISK_NAME_LEN, "bcache%i", minor); + snprintf(d->disk->disk_name, DISK_NAME_LEN, "bcache%i", + minor / BCACHE_MINORS); d->disk->major = bcache_major; d->disk->first_minor = minor; -- 2.7.4
