Ceph needs to be able to allocate inodes ahead of a create that might involve a fscrypt-encrypted inode. new_inode() almost fits the bill, but it puts the inode on the sb->s_inodes list and when we go to hash it, that might be done again. We could work around that by setting I_CREATING on the new inode, but that causes ilookup5 to return -ESTALE if something tries to find it before I_NEW is cleared. This is desirable behavior for most filesystems, but doesn't work for ceph. To work around all of this, just use new_inode_pseudo which doesn't add it to the sb->s_inodes list.
