From 3121bfe7631126d1b13064855ac2cfa164381bb0 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Thu, 9 Apr 2009 17:37:53 +0200 Subject: fuse: fix "direct_io" private mmap MAP_PRIVATE mmap could return stale data from the cache for "direct_io" files. Fix this by flushing the cache on mmap. Found with a slightly modified fsx-linux.
