Linux 2.6.32-rc1
in [Kernel]
|
From: Linus Torvalds on 27 Sep 2009 18:40 It's been two weeks (and then some - but with last week being LinuxCon and Plumbers conf I extended it by a few days), and as usual that means that the merge window is all over and done with. 2.6.32-rc1 is out, so give it a whirl. What can I say? 67% drivers (the bulk of which is from 'staging', but there's driver changes all over), 10% firmware, 10% arch updates (dominated by arm, but MIPS, POWER, SH and x86 updates are there too, along with the new 'SCore' architecture), 5% Documentation, and a random smattering of other things (ie the normal filesystem, kernel, networking etc updates). For a change, I don't think we have a single new filesystem this time around, but we do have updates to existing ones (ocfs2, btrfs, nfs, nilfs, xfs, gfs2, ext4 - you name it). Some of the more interesting changes (but perhaps that's just me) are some of the VM updates (ZERO_PAGE is back!) and the writeback work by Jens and others to spread out writeback by backing store. Go wild, test it out, and let us know about any regressions you find, Linus -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Of course, you realise that you set EXTRAVERSION to -rc2 :-( -- Cheers, Stephen Rothwell sfr(a)canb.auug.org.au http://www.canb.auug.org.au/~sfr/

I was going to apply a patch to -next to set it to -rc1, but I won't do that either. This way all bug reports are consistently confusing :-) -- Cheers, Stephen Rothwell sfr(a)canb.auug.org.au http://www.canb.auug.org.au/~sfr/

Following program should consume 10*8 seconds of cpu on a 8 cpu machine, but with 2.6.32-rc1 numbers are crazy. $ gcc -O2 -o process process.c -lpthread $ ./process PID TTY STAT TIME COMMAND 5532 pts/1 - 0:08 ./process - - Sl+ 0:00 - - - Rl+ 0:05 - - - Rl+ 0:05 - - - Rl+ 0:09 - - - Rl+ 0:05 - - - Rl+ 0:05 - - - Rl+ 0:05 - - - Rl+ 0:05 - - - Rl+ 0:01 - PID TTY STAT TIME COMMAND 5532 pts/1 - 0:16 ./process - - Sl+ 0:00 - - - Rl+ 0:14 - - - Rl+ 0:06 - - - Rl+ 0:14 - - - Rl+ 0:10 - - - Rl+ 0:06 - - - Rl+ 0:06 - - - Rl+ 0:10 - - - Rl+ 0:02 - PID TTY STAT TIME COMMAND 5532 pts/1 - 0:24 ./process - - Sl+ 0:00 - - - Rl+ 0:20 - - - Rl+ 0:11 - - - Rl+ 0:24 - - - Rl+ 0:15 - - - Rl+ 0:07 - - - Rl+ 0:07 - - - Rl+ 0:24 - - - Rl+ 0:03 - PID TTY STAT TIME COMMAND 5532 pts/1 - 0:32 ./process - - Sl+ 0:00 - - - Rl+ 0:29 - - - Rl+ 0:12 - - - Rl+ 0:29 - - - Rl+ 0:21 - - - Rl+ 0:08 - - - Rl+ 0:08 - - - Rl+ 0:29 - - - Rl+ 0:04 - PID TTY STAT TIME COMMAND 5532 pts/1 - 0:40 ./process - - Sl+ 0:00 - - - Rl+ 0:35 - - - Rl+ 0:13 - - - Rl+ 0:35 - - - Rl+ 0:26 - - - Rl+ 0:09 - - - Rl+ 0:09 - - - Rl+ 0:35 - - - Rl+ 0:05 - PID TTY STAT TIME COMMAND 5532 pts/1 - 0:48 ./process - - Sl+ 0:00 - - - Rl+ 0:40 - - - Rl+ 0:14 - - - Rl+ 0:40 - - - Rl+ 0:31 - - - Rl+ 0:10 - - - Rl+ 0:10 - - - Rl+ 0:40 - - - Rl+ 0:06 - PID TTY STAT TIME COMMAND 5532 pts/1 - 0:56 ./process - - Sl+ 0:00 - - - Rl+ 0:45 - - - Rl+ 0:15 - - - Rl+ 0:45 - - - Rl+ 0:37 - - - Rl+ 0:11 - - - Rl+ 0:11 - - - Rl+ 0:45 - - - Rl+ 0:07 - PID TTY STAT TIME COMMAND 5532 pts/1 - 1:05 ./process - - Sl+ 0:00 - - - Rl+ 0:51 - - - Rl+ 0:21 - - - Rl+ 0:55 - - - Rl+ 0:46 - - - Rl+ 0:12 - - - Rl+ 0:12 - - - Rl+ 0:59 - - - Rl+ 0:08 - PID TTY STAT TIME COMMAND 5532 pts/1 - 1:13 ./process - - Sl+ 0:00 - - - Rl+ 0:56 - - - Rl+ 0:22 - - - Rl+ 1:00 - - - Rl+ 0:52 - - - Rl+ 0:13 - - - Rl+ 0:13 - - - Rl+ 1:04 - - - Rl+ 0:09 - PID TTY STAT TIME COMMAND 5532 pts/1 - 5:13 ./process - - S+ 5:13 - $ cat process.c #include <pthread.h> #include <time.h> #include <stdio.h> /* * Burn cpu cycles for about 10 seconds */ static void *do_unit(void *arg) { time_t t0,t1; t0 = time(NULL); do { t1 = time(NULL); } while (t1 - t0 <= 10); return NULL; } int main(int argc, char *argv[]) { pthread_t tids[8]; int i; char cmd[128]; sprintf(cmd, "ps m -p %d", getpid()); for (i = 0; i < 8 ; i++) pthread_create(&tids[i], NULL, do_unit, NULL); for (i = 0; i < 9; i++) { sleep(1); system(cmd); } for (i = 0; i < 8 ; i++) pthread_join(tids[i], NULL); system(cmd); return 0; } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
