| |
Hello list,
in security/inode.c, the comment for securityfs_create_dir() reads:
If securityfs is not enabled in the kernel, the value -ENODEV will be returned. It is not wise to check for this value, but rather, check for NULL or !NULL instead as to eliminate the need for #ifdef in the calling code.
What is the actual callee that can return NULL - and what should module_init() of a module return when securityfs_create_dir() returns NULL?
Thanks, Jan -- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
