* [PATCH] simplify shmem_aops.set_page_dirty() methodKen Chen2007-02-11
| | | | | | | | | | | | | | | | | | | | | | | | shmem backed file does not have page writeback, nor it participates in backing device's dirty or writeback accounting. So using generic __set_page_dirty_nobuffers() for its .set_page_dirty aops method is a bit overkill. It unnecessarily prolongs shm unmap latency. For example, on a densely populated large shm segment (sevearl GBs), the unmapping operation becomes painfully long. Because at unmap, kernel transfers dirty bit in PTE into page struct and to the radix tree tag. The operation of tagging the radix tree is particularly expensive because it has to traverse the tree from the root to the leaf node on every dirty page. What's bothering is that radix tree tag is used for page write back. However, shmem is memory backed and there is no page write back for such file system. And in the end, we spend all that time tagging radix tree and none of that fancy tagging will be used. So let's simplify it by introduce a new aops __set_page_dirty_no_writeback and this will speed up shm unmap.

* [PATCH] zoneid: fix up calculations for ZONEID_PGSHIFTAndy Whitcroft2007-02-11
| | | | | | | | | | | | | | | | | | | | | Currently if we have a non-zero ZONES_SHIFT we assume we are able to rely on that as the bottom edge of the ZONEID, if not then we use the NODES_PGOFF as the right end of either NODES _or_ SECTION. This latter is more luck than judgement and would be incorrect if we reordered the SECTION,NODE,ZONE options in the fields space. Really what we want is the lower of the right hand end of the two fields we are using (either NODE,ZONE or SECTION,ZONE). Codify that explicitly. As always allow for there being no bits in either of the fields, such as might be valid in a non-numa machine with only a zone NORMAL. I have checked that the compiler is still able to constant fold all of this away correctly.

* [PATCH] Reorder ZVCs according to cachelineChristoph Lameter2007-02-11
| | | | | | | | | | | | The global and per zone counter sums are in arrays of longs. Reorder the ZVCs so that the most frequently used ZVCs are put into the same cacheline.

* [PATCH] Use ZVC for inactive and active countsChristoph Lameter2007-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The determination of the dirty ratio to determine writeback behavior is currently based on the number of total pages on the system. However, not all pages in the system may be dirtied. Thus the ratio is always too low and can never reach 100%. The ratio may be particularly skewed if large hugepage allocations, slab allocations or device driver buffers make large sections of memory not available anymore. In that case we may get into a situation in which f.e. the background writeback ratio of 40% cannot be reached anymore which leads to undesired writeback behavior. This patchset fixes that issue by determining the ratio based on the actual pages that may potentially be dirty. These are the pages on the active and the inactive list plus free pages. The problem with those counts has so far been that it is expensive to calculate these because counts from multiple nodes and multiple zones will have to be summed up. This patchset makes these counters ZVC counters. This means that a current sum per zone, per node and for the whole system is always available via global variables and not expensive anymore to calculate. The patchset results in some other good side effects: - Removal of the various functions that sum up free, active and inactive page counts - Cleanup of the functions that display information via the proc filesystem. This patch: The use of a ZVC for nr_inactive and nr_active allows a simplification of some counter operations. More ZVC functionality is used for sums etc in the following patches.

* devres: device resource managementTejun Heo2007-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement device resource management, in short, devres. A device driver can allocate arbirary size of devres data which is associated with a release function. On driver detach, release function is invoked on the devres data, then, devres data is freed. devreses are typed by associated release functions. Some devreses are better represented by single instance of the type while others need multiple instances sharing the same release function. Both usages are supported. devreses can be grouped using devres group such that a device driver can easily release acquired resources halfway through initialization or selectively release resources (e.g. resources for port 1 out of 4 ports). This patch adds devres core including documentation and the following managed interfaces. * alloc/free : devm_kzalloc(), devm_kzfree() * IO region : devm_request_region(), devm_release_region() * IRQ : devm_request_irq(), devm_free_irq() * DMA : dmam_alloc_coherent(), dmam_free_coherent(), dmam_declare_coherent_memory(), dmam_pool_create(), dmam_pool_destroy() * PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed() * iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(), devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(), pcim_iomap(), pcim_iounmap() Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

The counter has 14 bits of space, so if there are ever more than 16383, we cannot cope. Currently the code just calles BUG_ON as "all" drivers have request queue limits much smaller than this. However is seems that some don't. Apparently some multipath configurations can allow more than 16383 concurrent write requests. So, in this unlikely situation, instead of calling BUG_ON we now wait for the count to drop down a bit. This requires a new wait_queue_head, some waiting code, and a wakeup call. Tested by limiting the counter to 20 instead of 16383 (writes go a lot slower in that case...).

This was the wrong thing to do. I should have just set SK_CLOSE and let normal mechanisms do the work. Not only wrong, but buggy. The locking is all wrong and it openned up a race where-by a socket could be closed twice. So this patch: Introduces svc_close_socket which sets SK_CLOSE then either leave the close up to a thread, or calls svc_delete_socket if it can get SK_BUSY. Adds a bias to sk_busy which is removed when SK_DEAD is set, This avoid races around shutting down the socket. Changes several 'spin_lock' to 'spin_lock_bh' where the _bh was missing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a change for the EISA bus support to permit drivers to call un/registration functions even if EISA support has not been enabled. This is similar to what PCI (and now TC) does and reduces the need for #ifdef clutter. Signed-off-by: Maciej W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the platform-specific part of TURBOchannel bus support for the DECstation. It implements determining whether the bus is actually there, getting bus parameters, IRQ assignments for devices and protected accesses to possibly unoccupied slots that may trigger bus error exceptions.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a set of changes to convert support for the TURBOchannel bus to the driver model. It implements the usual set of calls similar to what other bus drivers have: tc_register_driver(), tc_unregister_driver(), etc. All the platform-specific bits have been removed and headers from asm-mips/dec/ have been merged into linux/tc.h, which should be included by drivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On all targets that sucker boils down to memcpy_fromio(sbk->data, from, len). The function name is highly misguiding (it _never_ does any checksums), the last argument is just a noise and simply expanding the call to memcpy_fromio() gives shorter and more readable source. For a lot of reasons it has almost no remaining users, so it's better to just outright kill it.
