last bullet of "The first in, first out policy"

The text says "When a process joins the FIFO class, or when a process' static priority changes, it is put at the head of the list of processes for its given priority. Consequently, a newly prioritized FIFO-classed process can preempt an executing process of the same priority."

This appears incorrect. The 2.6.22 implementation puts the process at the tail of the list. sched_setscheduler() calls __activate_task() calls enqueue_task() calls list_add_tail().

Note from the Author or Editor:
On p179, change:

"When a process joins the FIFO class, or when a process' static priority changes, it is put at the head of the list of processes for its given priority. Consequently, a newly prioritized FIFO-classed process can preempt an executing process of the same priority."

to

"When a process joins the FIFO class, or when a process's static priority changes, it is put at the tail of the list of processes for its given priority."

replaced the paragraph that begins starting with "The kernel stores
the limit ..." and ending with "... by that user" with this text -

The kernel manages the resource limits on a per-process basis. A child process inherits its limits
from its parent during fork; limits are maintained across exec.

1st paragraph

A preexisting erratum says, "(331) 1st paragraph;
Changed the repeated "seconds seconds" to just "seconds"
This is wrong--the first "seconds" is in a sans serif font, as it's a variable name from the preceding code snippet; i.e., its presence is correct. Better would be to (1) change the variable name in the snippet on the preceding page ("seconds") to something else (e.g. "secs"), and then (2) change the above to "secs seconds" (with "secs" in the sans serif font).
Note that the two fonts are rather too similar (which confused whoever wrote the erratum), and the code font should be bolder in the text, as it is in the code snippets introducing functions throughout the book. I'll add a (3) here, and suggest: Show ALL code samples (snippets as well as function intros) in the "emphasized" sans serif font. (Remember what we were taught as editing newbies--don't go crazy with the numerous font options available with your new word processor!)
...and now, back to reading my excellent book.
