bdflush

NAME
bdflush - start, flush, or tune buffe-dirt-flush daemon
SYNOPSIS
#include <sys/kdaemon.h>
int bdflush(int func, long data);
DESCRIPTION
This system call used to turn the calling process into the
bdflush
daemon,
or tune it,
or flush the "old buffers".
It then progressively lost all of that functionality.
See
fs/buffer.c
in the kernel version you're interested in to see what it actually does there.
ERRORS
ENOSYS
(this system call is unimplemented)
STANDARDS
Linux.
HISTORY
This system call was introduced in Linux 1.1.3,
became effectively obsolete in Linux 1.3.50,
mostly useless in Linux 2.3.23,
entirely useless in Linux 2.5.12,
officially deprecated in Linux 2.5.52,
and removed outright in Linux 5.15.
Sometimes, if
func
was even,
data
actually represented a pointer.
The header and prototype were removed in glibc 2.23.
