2006-03-25[PATCH] No need to protect current->group_info in sys_getgroups(), ↵Eric Dumazet
in_group_p() and in_egroup_p() While doing some benchmarks of an Apache/PHP SMP server, I noticed high oprofile numbers in in_group_p() and _atomic_dec_and_lock(). rank percent 1 4.8911 % __link_path_walk 2 4.8503 % __d_lookup *3 4.2911 % _atomic_dec_and_lock 4 3.9307 % __copy_to_user_ll 5 4.9004 % sysenter_past_esp *6 3.3248 % in_group_p It appears that in_group_p() does an uncessary get_group_info(current->group_info); /* atomic_inc() */ ... /* access current->group_info */ put_group_info(current->group_info); /* _atomic_dec_and_lock */ It is not necessary to do this, because the current task holds a reference on its own group_info, and this reference cannot change during the lookup. This patch deletes the get_group_info()/put_group_info() pair from sys_getgroups(), in_group_p() and in_egroup_p() functions.

2006-03-25[PATCH] Ext2 flags shouldn't report "nogrpid"Rob Landley
If I mount ext2 "rw", I want it to say "rw", not "rw,nogrpid". I caught this writing an automated regression test script for the busybox mount command. The symptom is /dev/loop0 on /images/ext2.dir type ext2 (rw,nogrpid) instead of: /dev/loop0 on /images/ext2.dir type ext2 (rw) The behavior was introduced by git commit 8fc2751beb0941966d3a97b26544e8585e428c08.

2006-03-25[PATCH] BLK_DEV_INITRD: do not require BLK_DEV_RAM=yZdenek Pavlas
Initramfs initrd images do not need a ramdisk device, so remove this restriction in Kconfig. BLK_DEV_RAM=n saves about 13k on i386. Also without ramdisk device there's no need for "dry run", so initramfs unpacks much faster. People using cramfs, squashfs, or gzipped ext2/minix initrd images are probably smart enough not to turn off ramdisk support by accident.

2006-03-25[PATCH] find_task_by_pid() needs tasklist_lockAndrew Morton
A couple of places are forgetting to take it. The kswapd case is probably unimportant. keventd_create_kthread() was racy. The whole thing is a bit flakey: you start a kernel thread, get its pid from kernel_thread() then look up its task_struct. a) It assumes that pid recycling takes a "long" time. b) We get a task_struct but no reference was taken on it. The owner of the kswapd and kthread task_struct*'s must assume that the new thread won't exit unexpectedly. Because if it does, they're left holding dead memory and any attempt to control or stop that task will crash.

2006-03-25[PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notificationsDavide Libenzi
Implement the half-closed devices notifiation, by adding a new POLLRDHUP (and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the existing POLLHUP handling, that does not report correctly half-closed devices, was feared to be changed, this implementation leaves the current POLLHUP reporting unchanged and simply add a new bit that is set in the few places where it makes sense. The same thing was discussed and conceptually agreed quite some time ago: http://lkml.org/lkml/2003/7/12/116 Since this new event bit is added to the existing Linux poll infrastruture, even the existing poll/select system calls will be able to use it. As far as the existing POLLHUP handling, the patch leaves it as is. The pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing archs and sets the bit in the six relevant files. The other attached diff is the simple change required to sys/epoll.h to add the EPOLLRDHUP definition. There is "a stupid program" to test POLLRDHUP delivery here: http://www.xmailserver.org/pollrdhup-test.c It tests poll(2), but since the delivery is same epoll(2) will work equally.

2006-03-25[PATCH] IRQ: prevent enabling of previously disabled interruptBryan Holty
This fix prevents re-disabling and enabling of a previously disabled interrupt. On an SMP system with irq balancing enabled; If an interrupt is disabled from within its own interrupt context with disable_irq_nosync and is also earmarked for processor migration, the interrupt is blindly moved to the other processor and enabled without regard for its current "enabled" state. If there is an interrupt pending, it will unexpectedly invoke the irq handler on the new irq owning processor (even though the irq was previously disabled) The more intuitive fix would be to invoke disable_irq_nosync and enable_irq, but since we already have the desc->lock from __do_IRQ, we cannot call them directly. Instead we can use the same logic to disable and enable found in disable_irq_nosync and enable_irq, with regards to the desc->depth. This now prevents a disabled interrupt from being re-disabled, and more importantly prevents a disabled interrupt from being incorrectly enabled on a different processor.
