Well that's very strange.

long do_sys_open(int dfd, const char __user *filename, int flags, int mode)
{
        char *tmp = getname(filename);
        int fd = PTR_ERR(tmp);

        if (!IS_ERR(tmp)) {
                fd = get_unused_fd();
                if (fd >= 0) {
============>           struct file *f = do_filp_open(dfd, tmp, flags, mode);
                        if (IS_ERR(f)) {
                                put_unused_fd(fd);
                                fd = PTR_ERR(f);
                        } else {
                                fsnotify_open(f->f_path.dentry);
                                fd_install(fd, f);
                        }
                }
                putname(tmp);
        }

do_filp_open has returned 0x8000002

Isn't that a SCSI error of some kind?

IAC we have tried to do fsnotify_open(f->f_path.dentry) with that result...
