Changes:
Cleaned a few printk's
Removed a meaningless ifndef.
Moved md= name_to_ kdev_t() processing from md_setup() to
md_setup_drive. Rewrote it and added devfs_find_handle() call
to support devfs names for md=.
The devfs_find_handle() code is now redundant in my patch and
fs/super.c::mount_root(). It probably should be moved directly into
name_to_kdev_t(), no? If this was done the md= code would have worked as is,
except for the devfs code choking on the trailing ',' in the device_names
list. (Richard, want to check for this in the future?)
This diff is against md.c in 2.4.4.
Comments/testing please.
Thanks to Neil Brown for the recommendation...
