Subject: page fault scalability patch V16 [2/4]: mm counter macros
Date: Fri, 28 Jan 2005 12:36:56 -0800 (PST) [thread overview]
Message-ID: <Pine.LNX.4.58.0501281236160.19266@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <Pine.LNX.4.58.0501281233560.19266@schroedinger.engr.sgi.com>
This patch extracts all the interesting pieces for handling rss and
anon_rss into definitions in include/linux/sched.h. All rss operations
are performed through the following three macros:
get_mm_counter(mm, member) -> Obtain the value of a counter
set_mm_counter(mm, member, value) -> Set the value of a counter
update_mm_counter(mm, member, value) -> Add a value to a counter
The simple definitions provided in this patch should result in no change to
to the generated code.
With this patch it becomes easier to add new counters and it is possible
to redefine the method of counter handling (f.e. the page fault scalability
patches may want to use atomic operations or split rss).
