2005-10-30[PATCH] block cleanups: Fix iosched module refcount leakNate Diller
If the requested I/O scheduler is already in place, elevator_switch simply leaves the queue alone, and returns. However, it forgets to call elevator_put, so 'echo [current_sched] > /sys/block/[dev]/queue/scheduler' will leak a reference, causing the current_sched module to be permanently pinned in memory.

2005-10-30[PATCH] reduce sizeof(struct file)Eric Dumazet
Now that RCU applied on 'struct file' seems stable, we can place f_rcuhead in a memory location that is not anymore used at call_rcu(&f->f_rcuhead, file_free_rcu) time, to reduce the size of this critical kernel object. The trick I used is to move f_rcuhead and f_list in an union called f_u The callers are changed so that f_rcuhead becomes f_u.fu_rcuhead and f_list becomes f_u.f_list Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-10-30[PATCH] cfq-iosched: move tasklist walk to elevator.cChristoph Hellwig
We're trying to get rid of as much as possible tasklist walks, or at least moving them to core code. This patch falls into the second category. Instead of walking the tasklist in cfq-iosched move that into elv_unregister. The added benefit is that with this change the as ioscheduler might be might unloadable more easily aswell. The new code uses read_lock instead of read_lock_irq because the tasklist_lock only needs irq disabling for writers.

2005-10-30[PATCH] create and destroy cpufreq sysfs entries based on cpu notifiersAshok Raj
cpufreq entries in sysfs should only be populated when CPU is online state. When we either boot with maxcpus=x and then boot the other cpus by echoing to sysfs online file, these entries should be created and destroyed when CPU_DEAD is notified. Same treatement as cache entries under sysfs. We place the processor in the lowest frequency, so hw managed P-State transitions can still work on the other threads to save power. Primary goal was to just make these directories appear/disapper dynamically. There is one in this patch i had to do, which i really dont like myself but probably best if someone handling the cpufreq infrastructure could give this code right treatment if this is not acceptable. I guess its probably good for the first cut. - Converting lock_cpu_hotplug()/unlock_cpu_hotplug() to disable/enable preempt. The locking was smack in the middle of the notification path, when the hotplug is already holding the lock. I tried another solution to avoid this so avoid taking locks if we know we are from notification path. The solution was getting very ugly and i decided this was probably good for this iteration until someone who understands cpufreq could do a better job than me.

2005-10-30[PATCH] introduce get_cpu_sysdev() to retrieve a sysfs entry for a cpu.Ashok Raj
Some modules creating sysfs entries under /sys/devices/system/cpu/cpuX/ need to know the parent sysfs entry to make devices under them. This will just return the sysfs entry for a given cpu. sysfs entries showing under each cpu sysfs can be easily created if such entries can be created by registering a sysfs driver for cpuclass. The issue is when the entry is created the CPU may not be online, hence we would need to defer the creation until the online notification comes. Current users: cache entries for Intel CPU's and cpufreq subsystem.

2005-10-30[libata] fix legacy IDE probingJeff Garzik
ata_pci_init_one() receives an array of struct ata_port_info. Recent updates to the code had always obtained port information from array element 0, rather than array element N. Change to avoid hardcoding port_info[0], thereby restoring proper hardware information to secondary legacy ports.
2005-10-30[libata] change ata_qc_complete() to take error mask as second argJeff Garzik
The second argument to ata_qc_complete() was being used for two purposes: communicate the ATA Status register to the completion function, and indicate an error. On legacy PCI IDE hardware, the latter is often implicit in the former. On more modern hardware, the driver often completely emulated a Status register value, passing ATA_ERR as an indication that something went wrong. Now that previous code changes have eliminated the need to use drv_stat arg to communicate the ATA Status register value, we can convert it to a mask of possible error classes. This will lead to more flexible error handling in the future.

2005-10-29[PATCH] memory hotplug: move section_mem_map alloc to sparse.cDave Hansen
This basically keeps up from having to extern __kmalloc_section_memmap(). The vaddr_in_vmalloc_area() helper could go in a vmalloc header, but that header gets hard to work with, because it needs some arch-specific macros.

2005-10-29[PATCH] core remove PageReservedNick Piggin
Remove PageReserved() calls from core code by tightening VM_RESERVED handling in mm/ to cover PageReserved functionality. PageReserved special casing is removed from get_page and put_page. All setting and clearing of PageReserved is retained, and it is now flagged in the page_alloc checks to help ensure we don't introduce any refcount based freeing of Reserved pages. MAP_PRIVATE, PROT_WRITE of VM_RESERVED regions is tentatively being deprecated. We never completely handled it correctly anyway, and is be reintroduced in future if required (Hugh has a proof of concept). Once PageReserved() calls are removed from kernel/power/swsusp.c, and all arch/ and driver code, the Set and Clear calls, and the PG_reserved bit can be trivially removed. Last real user of PageReserved is swsusp, which uses PageReserved to determine whether a struct page points to valid memory or not. This still needs to be addressed (a generic page_is_ram() should work). A last caveat: the ZERO_PAGE is now refcounted and managed with rmap (and thus mapcounted and count towards shared rss). These writes to the struct page could cause excessive cacheline bouncing on big systems. There are a number of ways this could be addressed if it is an issue.
