Date: Fri, 17 Feb 2017 11:30:10 +0300 From: Cyrill Gorcunov <gorcunov@...nvz.org> To: linux-fsdevel@...r.kernel.org, linux-kernel@...r.kernel.org, linux-api@...r.kernel.org Cc: viro@...iv.linux.org.uk, akpm@...uxfoundation.org, avagin@...tuozzo.com, xemul@...tuozzo.com, mtk.manpages@...il.com, kir@...nvz.org, gorcunov@...nvz.org Subject: [RFC 0/2] fs,eventpoll: Add EPOLL_CTL_DUP into epoll_ctl syscall In the series new EPOLL_CTL_DUP operation introduced, we need it to be able to restore target file descriptors in case if they were dup'ed (or received via unix message) before registering and closed after, so the fdinfo info shows file number which application no longer having. Please take a look. Kir, I slightly updated manpage to mention the reason why we need this operation. Cyrill
