Hmm, not sure I want people renaming the filesystem to something
else, why do you want to do this?
However, the reason it did not work is that the part of the kernel
which cares about the name of the filesystem is not using that
constant. In fs/xfs/linux/xfs_super.c look for this:
STATIC struct file_system_type xfs_fs_type = {
.owner = THIS_MODULE,
.name = "xfs",
.read_super = linvfs_read_super,
.fs_flags = FS_REQUIRES_DEV,
};
That string in there is the fstype used by mount. You would
have to use mount -t to make this work I think. I am not sure
where the string is coming from when mount works out the fs
type by itself - probably it is hard coded into the mount
source code.
