    kobject: Always build in kernel/ksysfs.o. · dfacd68e
    Paul Mundt authored
    kernel/ksysfs.c seems to be a random dumping group for misc globals
    that the rest of the tree depend on. This has caused problems with
    exports in the past when sysfs is disabled, which can already be
    observed in commit-id 51107301.
    
    The latest one is the kernel_kobj usage, which presently results in:
    
    fs/built-in.o: In function `debugfs_init':
    inode.c:(.init.text+0xc34): undefined reference to `kernel_kobj'
    make: *** [.tmp_vmlinux1] Error 1
    
    kernel/ksysfs.c itself at this point only contains globals and some
    basic sysfs initialization, the sysfs initialization code is optimized
    out when we build with sysfs disabled. Given that, it's easier to just
    build in unconditionally, rather than trying to find some other random
    place to dump and initialize the globals.
    
    Additionally, the current trend seems to be decoupling of kobjects from
    sysfs, in which case it still makes sense to perform the kernel_kobj
    initialization that happens here even if sysfs is disabled, as
    lib/kobject.o is built-in unconditionally.
