 	Valid values for this option are page size (typically 4KiB)
 	through to 1GiB, inclusive, in power-of-2 increments.
 
-  attr2/noattr2
-	The options enable/disable (default is disabled for backward
-	compatibility on-disk) an "opportunistic" improvement to be
-	made in the way inline extended attributes are stored on-disk.
-	When the new form is used for the first time (by setting or
-	removing extended attributes) the on-disk superblock feature
-	bit field will be updated to reflect this format being in use.
+	The default behaviour is for dynamic end-of-file
+	preallocation size, which uses a set of heuristics to
+	optimise the preallocation size based on the current
+	allocation patterns within the file and the access patterns
+	to the file. Specifying a fixed allocsize value turns off
+	the dynamic behaviour.
+
+  attr2
+  noattr2
+	The options enable/disable an "opportunistic" improvement to
+	be made in the way inline extended attributes are stored
+	on-disk.  When the new form is used for the first time when
+	attr2 is selected (either when setting or removing extended
+	attributes) the on-disk superblock feature bit field will be
+	updated to reflect this format being in use.
+
+	The default behaviour is determined by the on-disk feature
+	bit indicating that attr2 behaviour is active. If either
+	mount option it set, then that becomes the new default used
+	by the filesystem.
 
 	CRC enabled filesystems always use the attr2 format, and so
 	will reject the noattr2 mount option if it is set.
 
-  barrier
-	Enables the use of block layer write barriers for writes into
-	the journal and unwritten extent conversion.  This allows for
-	drive level write caching to be enabled, for devices that
-	support write barriers.
+  barrier (*)
+  nobarrier
+	Enables/disables the use of block layer write barriers for
+	writes into the journal and for data integrity operations.
+	This allows for drive level write caching to be enabled, for
+	devices that support write barriers.
 
   discard
-	Issue command to let the block device reclaim space freed by the
-	filesystem.  This is useful for SSD devices, thinly provisioned
-	LUNs and virtual machine images, but may have a performance
-	impact.
-
-  dmapi
-	Enable the DMAPI (Data Management API) event callouts.
-	Use with the "mtpt" option.
-
-  grpid/bsdgroups and nogrpid/sysvgroups
-	These options define what group ID a newly created file gets.
-	When grpid is set, it takes the group ID of the directory in
-	which it is created; otherwise (the default) it takes the fsgid
-	of the current process, unless the directory has the setgid bit
-	set, in which case it takes the gid from the parent directory,
-	and also gets the setgid bit set if it is a directory itself.
-
-  ihashsize=value
-	In memory inode hashes have been removed, so this option has
-	no function as of August 2007. Option is deprecated.
-
-  ikeep/noikeep
-	When ikeep is specified, XFS does not delete empty inode clusters
-	and keeps them around on disk. ikeep is the traditional XFS
-	behaviour. When noikeep is specified, empty inode clusters
-	are returned to the free space pool. The default is noikeep for
-	non-DMAPI mounts, while ikeep is the default when DMAPI is in use.
-
-  inode64
-	Indicates that XFS is allowed to create inodes at any location
-	in the filesystem, including those which will result in inode
-	numbers occupying more than 32 bits of significance.  This is
-	the default allocation option. Applications which do not handle
-	inode numbers bigger than 32 bits, should use inode32 option.
+  nodiscard (*)
+	Enable/disable the issuing of commands to let the block
+	device reclaim space freed by the filesystem.  This is
+	useful for SSD devices, thinly provisioned LUNs and virtual
+	machine images, but may have a performance impact.
+
+	Note: It is currently recommended that you use the fstrim
+	application to discard unused blocks rather than the discard
+	mount option because the performance impact of this option
+	is quite severe.
+
+  grpid/bsdgroups
+  nogrpid/sysvgroups (*)
+	These options define what group ID a newly created file
+	gets.  When grpid is set, it takes the group ID of the
+	directory in which it is created; otherwise it takes the
+	fsgid of the current process, unless the directory has the
+	setgid bit set, in which case it takes the gid from the
+	parent directory, and also gets the setgid bit set if it is
+	a directory itself.
+
+  filestreams
+	Make the data allocator use the filestreams allocation mode
+	across the entire filesystem rather than just on directories
+	configured to use it.
+
+  ikeep
+  noikeep (*)
+	When ikeep is specified, XFS does not delete empty inode
+	clusters and keeps them around on disk.  When noikeep is
+	specified, empty inode clusters are returned to the free
+	space pool.
 
   inode32
-	Indicates that XFS is limited to create inodes at locations which
-	will not result in inode numbers with more than 32 bits of
-	significance. This is provided for backwards compatibility, since
-	64 bits inode numbers might cause problems for some applications
-	that cannot handle large inode numbers.
-
-  largeio/nolargeio
+  inode64 (*)
+	When inode32 is specified, it indicates that XFS limits
+	inode creation to locations which will not result in inode
+	numbers with more than 32 bits of significance.
+
+	When inode64 is specified, it indicates that XFS is allowed
+	to create inodes at any location in the filesystem,
+	including those which will result in inode numbers occupying
+	more than 32 bits of significance. 
+
+	inode32 is provided for backwards compatibility with older
+	systems and applications, since 64 bits inode numbers might
+	cause problems for some applications that cannot handle
+	large inode numbers.  If applications are in use which do
+	not handle inode numbers bigger than 32 bits, the inode32
+	option should be specified.
+
+
+  largeio
+  nolargeio (*)
 	If "nolargeio" is specified, the optimal I/O reported in
-	st_blksize by stat(2) will be as small as possible to allow user
-	applications to avoid inefficient read/modify/write I/O.
-	If "largeio" specified, a filesystem that has a "swidth" specified
-	will return the "swidth" value (in bytes) in st_blksize. If the
-	filesystem does not have a "swidth" specified but does specify
-	an "allocsize" then "allocsize" (in bytes) will be returned
-	instead.
-	If neither of these two options are specified, then filesystem
-	will behave as if "nolargeio" was specified.
+	st_blksize by stat(2) will be as small as possible to allow
+	user applications to avoid inefficient read/modify/write
+	I/O.  This is typically the page size of the machine, as
+	this is the granularity of the page cache.
+
+	If "largeio" specified, a filesystem that was created with a
+	"swidth" specified will return the "swidth" value (in bytes)
+	in st_blksize. If the filesystem does not have a "swidth"
+	specified but does specify an "allocsize" then "allocsize"
+	(in bytes) will be returned instead. Otherwise the behaviour
+	is the same as if "nolargeio" was specified.
 
   logbufs=value
-	Set the number of in-memory log buffers.  Valid numbers range
-	from 2-8 inclusive.
-	The default value is 8 buffers for filesystems with a
-	blocksize of 64KiB, 4 buffers for filesystems with a blocksize
-	of 32KiB, 3 buffers for filesystems with a blocksize of 16KiB
-	and 2 buffers for all other configurations.  Increasing the

+	Set the number of in-memory log buffers.  Valid numbers

+
+	The default value is 8 buffers.
+
+	If the memory cost of 8 log buffers is too high on small
+	systems, then it may be reduced at some cost to performance
+	on metadata intensive workloads. The logbsize option below
+	controls the size of each buffer and so is also relevent to
+	this case.
 
   logbsize=value
-	Set the size of each in-memory log buffer.

+
+	The sunit and swidth parameters specified must be compatible

   swalloc
 	Data allocations will be rounded up to stripe width boundaries
 	when the current end of file is being extended and the file
 	size is larger than the stripe width size.
 
+  wsync
+	When specified, all filesystem namespace operations are
+	executed synchronously. This ensures that when the namespace
+	operation (create, unlink, etc) completes, the change to the
+	namespace is on stable storage. This is useful in HA setups
+	where failover must not result in clients seeing
+	inconsistent namespace presentation during or after a
