[dm-devel] [PATCH] 2.6.0-test3: Use format_dev_t

[Kevin Corry]

This patch changes dm-linear and dm-stripe to use the new format_dev_t(),
defined in include/linux/kdev_t.h, instead of bdevname() when printing target
parameters.

format_dev_t() is very similar to dm_bdevname() in 2.4 (which has also been
proposed for 2.6). The print formats used are:
dm_bdevname:  %03d:%03d
format_dev_t:  %u:%u

Is there a reason DM needs zero-filled, 3-digit numbers for major and minor?
If not, format_dev_t() seems like it will be the preferred method for printing
device numbers in 2.6.
