All,
This Memorial Day, take a moment to remember the source code that has
served in our kernel since its inception. To this end, wander by
http://minnie.tuhs.org/UnixTree/, and pause for a moment to commemorate
these brave functions from the 101st Tapeborne -- all of which have
served continuously since August, 1973:
bflush() falloc() newproc() sched()
bread() getblk() nodev() signal()
brelse() getf() nulldev() stty()
bwrite() gtty() panic() suser()
clock() issig() printf() swtch()
closef() mmread() psig() timeout()
core() mmwrite() psignal() ufalloc()
Their compatriot structure fields include:
av_back b_flags p_flag u_cdir
av_forw b_forw p_ppid
b_back c_arg (*) p_stat
b_blkno c_func (*) p_wchan
(*) c_func and c_arg are notable for having survived a bonwick scorched-earth
rewrite of callouts circa 1997 -- unclear if this makes them eligible for
the Purple Heart, or if they should be considered acquited war criminals.
As for constants, B_DONE, B_ERROR, FREAD, FWRITE, and SSLEEP have all had the
same numerical value since they enlisted in 1973. And a moment of silence
is certainly due to this line in proc.h -- a line which has not changed
so much as a character since 1973:
/* stat codes */
And to the code ripped out in the line of duty, we say only: "We Have Not
Forgotten." (Of course, we usually follow that up with "Never Again.")
