Technically we should never have a problem, though, since we only use this for the journal inode, which is not going to be a fresly created inode. So I don't think we should ever hit the paths that will result in the kernel sleeping. But I agree it's better to move it out, if for no other reason to make life easier for static checkers. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
