From 9af36b95976d4e54859c9b60bd2e711518b3be6e Mon Sep 17 00:00:00 2001 From: Krutika Dhananjay Date: Mon, 2 May 2016 16:51:10 +0530 Subject: core, shard: Make shards inherit main file's O_DIRECT flag if present Backport of: http://review.gluster.org/14191 If the application opens a file with O_DIRECT, the shards' anon fds would also need to inherit the flag. Towards this, shard xl would be passing the odirect flag in the @flags parameter to the WRITEV fop. This will be used in anon fd resolution and subsequent opening by posix xl.
