sysfs: Store the sysfs inode in an unsigned int.
Store the sysfs inode number in an unsided int because ida inode allocator can return at most a 31 bit number, reducing the size of struct sysfs_dirent by 8 bytes on 64bit platforms. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
