From d4ffff1fa9695c5b5c0bf337e208d8833b88ff2d Mon Sep 17 00:00:00 2001 From: Pavel Shilovsky Date: Thu, 26 May 2011 06:02:00 +0000 Subject: [PATCH] CIFS: Add rwpidforward mount option Add rwpidforward mount option that switches on a mode when we forward pid of a process who opened a file to any read and write operation. This can prevent applications like WINE from failing on read or write operation on a previously locked file region from the same netfd from another process if we use mandatory brlock style. It is actual for WINE because during a run of WINE program two processes work on the same netfd - share the same file struct between several VFS fds: 1) WINE-server does open and lock; 2) WINE-application does read and write.
