No, the inode is not NULL, it has been allocated in ram at adress 0x4654a0
and most of fields have been initialized.
d_inode->i_op->setattr = <ramfs_nommu_setattr>
d_inode->i_op->getattr = <simple_getattr>

I am using initramfs support to mount VFS, not init ramdisk (initrd)
If I well understand, in my case I have not to deal with precompiled
I only provide a config file to the CONFIG_INITRAMFS_SOURCE option.

Indeed, I dug in the source code, I agree with this.
Unfortunalety, when debugging, it appears that inode->i_op->getxattr
But I am confused.. for example, what the difference (in the .config file)
"File systems" and "Pseudo filesystems" menus?
Because we are speaking about my VFS, so at the moment, the kind of
the filesystem is not really important for me.
What the difference if I choose ramfs instead of ext2 for example?
I have some shadow zones that make me confused..
Thanks for your help.
