Description Top

From "The magic garden explained":

fsflush is a system process started at system boot.  It is awoken
each second in clock() to flush cached data to its storage device. 
This includes the system's buffer cache, in-core inode cache and
mapped-in memory pages.  To bring some form of data integrity to 
the UNIX file subsystem implementation, the designers chose to
flush the in-core inode tables of each file system each second
from fsflush.  This mechanism is known as "file system hardening".
