SVN rev 213526 on 2010-10-07 18:00:55Z by jh
Check the device name validity on device registration.
A new function prep_devname() sanitizes a device name by removing
leading and redundant sequential slashes. The function returns an error
for names which already exist or are considered invalid.
A new flag MAKEDEV_CHECKNAME for make_dev_p(9) and make_dev_credf(9)
indicates that the caller is prepared to handle an error related to the
device name. An invalid name triggers a panic if the flag is not
specified.
Document the MAKEDEV_CHECKNAME flag in the make_dev(9) manual page.
