If we get a memory allocation failure, there's already going to be a lot of spew in the logs from the mm system. And if we do fail to allocate memory, we don't need to know the logical block number or the nid -- it has nothiing to do with those; the system simply ran out of memory. > + err = -ENOMEM; > + break; > + } else if (IS_ERR(dentry_page)) { > + errln("fail to readdir of logical block %u of nid %llu", > + i, EROFS_V(dir)->nid); > + err = -EFSCORRUPTED; > + break; > + } > > de = (struct erofs_dirent *)kmap(dentry_page); > > -- > 2.17.1 >
