From dccae99995089641fbac452ebc7f0cab18751ddb Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Thu, 2 Apr 2009 16:59:01 -0400 Subject: [PATCH] Btrfs: add flushoncommit mount option The 'flushoncommit' mount option forces any data dirtied by a write in a prior transaction to commit as part of the current commit. This makes the committed state a fully consistent view of the file system from the application's perspective (i.e., it includes all completed file system operations). This was previously the behavior only when a snapshot is created. This is used by Ceph to ensure that completed writes make it to the platter along with the metadata operations they are bound to (by BTRFS_IOC_TRANS_{START,END}).
