And I'm sorry, but I'm not sure what is going on in the code, so I don't want to close this here by just removing those flags from the manual page, because I worry that the actual code may be wrong or something. So I prefer that when Michael has some time he can maybe review this and say something. Ideally, someone from the kernel would also respond, but they haven't. I've CCd the LKML; let's see if someone reads this and can help. Thanks, Alex P.S.: Please, if we haven't responded in a month from now, ping us again. Thanks again. > > // Erik > >> >> -- >> Alejandro Colomar >> Linux man-pages comaintainer; https://www.kernel.org/doc/man-pages/ >> http://www.alejandro-colomar.es/ -- Alejandro Colomar Linux man-pages comaintainer; https://www.kernel.org/doc/man-pages/ http://www.alejandro-colomar.es/
