	DESCRIPTION
	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.
	OPTIONS
	
		
		commit:dthresh = BYTES
		
		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
		
		
		
	
	EXAMPLES
	Synchronize the file data on the [precious] share after
	every 512 kilobytes (524288 bytes) of data is written:
        
	/data/precious
	commit
	512K
	CAVEATS
	On some systems, the data synchronization performed by
	commit may reduce performance.

	AUTHOR
	The original Samba software and related utilities
	were created by Andrew Tridgell. Samba is now developed
	by the Samba Team as an Open Source project similar
	to the way the Linux kernel is developed.
