||What is the purpose of fsflush?
||12 May 1998
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".
