vfs_commit — flush dirty data at specified intervals
vfs objects = commit
This VFS module is part of the samba(7) suite.
The vfs_commit VFS module keeps track of
	the amount of data written to a file and synchronizes it to
	disk when a specified amount accumulates.
	
vfs_commit is useful in two
	circumstances. First, if you have very precious data, the
	impact of unexpected power loss can be minimized by a small
	commit:dthresh value. Secondly, write performance can be
	improved on some systems by flushing file data early and at
	regular intervals.
This module is stackable.
Synchronize file data each time the specified number of bytes has been written.
The following suffixes may be applied to BYTES:
K - BYTES is a number of kilobytes
M - BYTES is a number of megabytes
G - BYTES is a number of gigabytes
Synchronize the file data on the [precious] share after every 512 kilobytes (524288 bytes) of data is written:
        [precious]
	path = /data/precious
	vfs objects = commit
	commit:dthresh = 512K
