If any entry attributes have been looked up by the + * time userspace requests the next batch of entries continue with + * READDIRPLUS, otherwise switch to plain READDIR. This will reasult + * in eg plain "ls" triggering READDIRPLUS first then READDIR after + * that because it doesn't do lookups. "ls -l" should result in all + * READDIRPLUS, except if dentries are already cached. + * * This feature is enabled by default when supported by the kernel and * if the filesystem implements both a readdirplus() and a readdir() * handler. |
