-.Dt FFS_SOFTUPDATES 4
-.Os
-.Sh NAME
-.Nm ffs_softupdates
-.Nd asynchronous file system writes
-.Sh DESCRIPTION
-The
-.Nm FFS_SOFTUPDATES
-kernel config option enables a scheme that uses partial ordering of
-buffer cache operations to allow metadata updates in the fast filesystem
-to happen asynchronously, increasing write performance significantly.
-Normally, the
-.Em ffs
-filesystem writes metadata updates synchronously which exacts
-a performance penalty in favor of filesystem integrity.
-With
-.Em soft updates ,
-you gain the performance of asynchronous writes while retaining the safety
-of synchronous metadata updates.
-.Pp
-.Em Soft Updates
-must be enabled on a per-filesystem basis. To do this, boot into
-single user mode and run
-.Dq tunefs -s enable special
-on each character special disk device you want to enable
-.Em soft updates
-on, then run
-.Dq reboot -n .
-.Sh CAVEATS
-Soft updates should be considered experimental at this time.
-.Pp
-CPUs with a small kernel address space, such as the sun4 and
-sun4c, do not have enough kernel memory to support
-.Em Soft Updates .
-Attempts to use
-.Em Soft Updates
-on these CPUs will cause a kernel hang or panic after a short period of
-use as the kernel will quickly run out of memory. This is not related
-to the amount of physical memory present in the machine--it is a limitation
-of the CPU architecture.
-.Pp
-There should be a
-.Xr mount 2
-option to enable
-.Em soft updates .
-.br
-The current license for
-.Nm
-is more restrictive than the rest of the
-.Ox
-kernel; this will be changed at a future date.
