Hello,
I think a line ".owner = THIS_MODULE," should be
inserted at http://lxr.linux.no/source/fs/ramfs/inode.c#L216 .
Without this line, ramfs can't work safely as a module, for
it doesn't increment module usage counter,
resulting successful rmmod while ramfs is mounted
and subsequent crash.
I know ramfs in 2.6 are always built into kernel,
but someone would get troubled when
examining ramfs code for study purpose.
Best Regards.
