Re: Q: BUG_ON __GFP_HIGHMEM [FIXED!]

Hello again,

I fixed the error myself by calling inode_nohighmem when we initialize the inode.

/Bo Branten

/*
 * Allocate a new inode (of the file system identified by `sb') and
 * return it, associated with `newnode'.  Return the `inode' or NULL.
 * The reference count on `inode' is incremented.
 */

static void
nnpfs_fill_inode(struct inode *inode, struct nnpfs_msg_node *node)
{
    struct nnpfs_attr *attr = &node->attr;

    if (!XA_VALID_TYPE(attr)) {
        inode->i_op  = &nnpfs_dead_inode_operations;
        inode->i_fop = &nnpfs_dead_operations;
    } else if (attr->xa_type == NNPFS_FILE_REG) {
        inode->i_op  = &nnpfs_file_inode_operations;
        inode->i_fop = &nnpfs_file_operations;
        inode->i_mapping->a_ops = &nnpfs_aops;
    } else if (attr->xa_type == NNPFS_FILE_DIR) {
        inode->i_op  = &nnpfs_dir_inode_operations;
        inode->i_fop = &nnpfs_dir_operations;
        inode->i_mapping->a_ops = &nnpfs_aops;
    } else if (attr->xa_type == NNPFS_FILE_LNK) {
        inode->i_op  = &nnpfs_link_inode_operations;
        inode->i_fop = &nnpfs_link_operations;
        inode->i_mapping->a_ops = &nnpfs_aops;
#if LINUX_VERSION_CODE >= KERNEL_VERSION(4,5,0)
        inode_nohighmem(inode);
#endif
    } else {
        inode->i_op  = &nnpfs_dead_inode_operations;
        inode->i_fop = &nnpfs_dead_operations;
    }
}
