* define page_file_cache() functionRik van Riel2008-10-207-2/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Define page_file_cache() function to answer the question: is page backed by a file? Originally part of Rik van Riel's split-lru patch. Extracted to make available for other, independent reclaim patches. Moved inline function to linux/mm_inline.h where it will be needed by subsequent "split LRU" and "noreclaim" patches. Unfortunately this needs to use a page flag, since the PG_swapbacked state needs to be preserved all the way to the point where the page is last removed from the LRU. Trying to derive the status from other info in the page resulted in wrong VM statistics in earlier split VM patchsets. The total number of page flags in use on a 32 bit machine after this patch is 19.

* vmscan: free swap space on swap-in/activationRik van Riel2008-10-205-3/+60
| | | | | | | | | | | | | If vm_swap_full() (swap space more than 50% full), the system will free swap space at swapin time. With this patch, the system will also free the swap space in the pageout code, when we decide that the page is not a candidate for swapout (and just wasting swap space).

* swap: use an array for the LRU pagevecsKOSAKI Motohiro2008-10-204-66/+55
| | | | | | | | | | | | Turn the pagevecs into an array just like the LRUs. This significantly cleans up the source code and reduces the size of the kernel by about 13kB after all the LRU lists have been created further down in the split VM patch series.

* vmscan: Use an indexed array for LRU variablesChristoph Lameter2008-10-208-170/+171
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we are defining explicit variables for the inactive and active list. An indexed array can be more generic and avoid repeating similar code in several places in the reclaim code. We are saving a few bytes in terms of code size: Before: text data bss dec hex filename 4097753 573120 4092484 8763357 85b7dd vmlinux After: text data bss dec hex filename 4097729 573120 4092484 8763333 85b7c5 vmlinux Having an easy way to add new lru lists may ease future work on the reclaim code.

* vmscan: move isolate_lru_page() to vmscan.cNick Piggin2008-10-206-37/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On large memory systems, the VM can spend way too much time scanning through pages that it cannot (or should not) evict from memory. Not only does it use up CPU time, but it also provokes lock contention and can leave large systems under memory presure in a catatonic state. This patch series improves VM scalability by: 1) putting filesystem backed, swap backed and unevictable pages onto their own LRUs, so the system only scans the pages that it can/should evict from memory 2) switching to two handed clock replacement for the anonymous LRUs, so the number of pages that need to be scanned when the system starts swapping is bound to a reasonable number 3) keeping unevictable pages off the LRU completely, so the VM does not waste CPU time scanning them. ramfs, ramdisk, SHM_LOCKED shared memory segments and mlock()ed VMA pages are keept on the unevictable list. This patch: isolate_lru_page logically belongs to be in vmscan.c than migrate.c. It is tough, because we don't need that function without memory migration so there is a valid argument to have it in migrate.c. However a subsequent patch needs to make use of it in the core mm, so we can happily move it to vmscan.c. Also, make the function a little more generic by not requiring that it adds an isolated page to a given list. Callers can do that. Note that we now have '__isolate_lru_page()', that does something quite different, visible outside of vmscan.c for use with memory controller. Methinks we need to rationalize these names/purposes. --lts [akpm@linux-foundation.org: fix mm/memory_hotplug.c build] Signed-off-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Rik van Riel <riel@redhat.com> Signed-off-by: Lee Schermerhorn <Lee.Schermerhorn@hp.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* anon_vma_prepare: properly lock even newly allocated entriesLinus Torvalds2008-10-191-10/+32
| | | | | | | | | | | | | | | | | | | | The anon_vma code is very subtle, and we end up doing optimistic lookups of anon_vmas under RCU in page_lock_anon_vma() with no locking. Other CPU's can also see the newly allocated entry immediately after we've exposed it by setting "vma->anon_vma" to the new value. We protect against the anon_vma being destroyed by having the SLAB marked as SLAB_DESTROY_BY_RCU, so the RCU lookup can depend on the allocation not being destroyed - but it might still be free'd and re-allocated here to a new vma. As a result, we should not do the anon_vma list ops on a newly allocated vma without proper locking.

| * USB: OHCI: fix endless polling behaviorAlan Stern2008-10-171-19/+32

In the current code, if the RHSC interrupt status flag turns on at a time when RHSC interrupts are disabled, it will remain on forever: The interrupt handler is the only place where RHSC status gets turned back off; The interrupt handler won't turn RHSC status off because it doesn't turn off status flags if the corresponding interrupt isn't enabled; RHSC interrupts will never get enabled because ohci_root_hub_state_changes() doesn't reenable RHSC if RHSC status is on! As a result we will continue polling indefinitely instead of reverting to interrupt-driven operation, and the root hub will not autosuspend. This particular sequence of events is not at all unusual; in fact plugging a USB device into an OHCI controller will usually cause it to occur. Of course, this is a bug. The proper thing to do is to turn off RHSC status just before reading the actual port status values. That way either a port status change will be detected (if it occurs before the status read) or it will turn RHSC back on. Possibly both, but that won't hurt anything. We can still check for systems in which RHSC is totally broken, by re-reading RHSC after clearing it and before reading the port statuses. (This re-read has to be done anyway, to post the earlier write.) If RHSC is on but no port-change statuses are set, then we know that RHSC is broken and we can avoid re-enabling it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds initial_descriptor_timeout module parameter for usbcore.ko to allow modify initial 64-byte USB_REQ_GET_DESCRIPTOR timeout for non-standard devices. For example, the SATA8000 device from DATAST0R Technology Corp requires about 10 seconds to send reply (probably it waits until inserted disk is ready for operation). Also, this patch adds missing usbcore parameters to Documentation/kernel-parameters.txt.

| * USB: Export if an interface driver supports autosuspend.Sarah Sharp2008-10-172-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create a new sysfs file per interface named supports_autosuspend. This file returns true if an interface driver's .supports_autosuspend flag is set. It also returns true if the interface is unclaimed (since the USB core will autosuspend a device if an interface is not claimed). This new sysfs file will be useful for user space scripts to test whether a USB device correctly auto-suspends.

| * USB: EHCI: fix remote-wakeup support for ARC/TDI coreAlan Stern2008-10-173-14/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1147) fixes the remote-wakeup support for EHCI controllers using the ARC/TDI "embedded-TT" core. These controllers turn off the RESUME bit by themselves when a port resume is complete; hence we need to keep separate track of which ports are suspended or in the process of resuming. The patch also makes a couple of small improvements in ehci_irq(), replacing reads of the command register with the value already stored in a local variable.

| * USB: snoop processes opening usbfs device filesAlan Stern2008-10-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | This patch (as1148) adds a new "snoop" message to usbfs when a device file is opened, identifying the process responsible. This comes in extremely handy when trying to determine which program is doing some unwanted USB access.

| | | | | | | | | | | | | | | | | | | | | | | | This patch (as1139) adds a warning to the system log whenever ehci-hcd is loaded after ohci-hcd or uhci-hcd. Nowadays most distributions are pretty good about not doing this; maybe the warning will help convince anyone still doing it wrong.

| | | | | | | | | | | | | | | | | | | | | | This patch (as1145) removes the essentially useless driver-version strings from ehci-hcd, ohci-hcd, and uhci-hcd. It also unifies the form of the banner lines they display upon loading and adds a missing test for usb_disabled() to ehci-hcd.
