'struct page' has two list_head fields: 'lru' and 'list'. Conveniently, they are unioned together. This means that code can use them interchangably, which gets horribly confusing like with this nugget from slab.c: > list_del(&page->lru); > if (page->active == cachep->num) > list_add(&page->list, &n->slabs_full); This patch makes the slab and slub code use page->lru universally instead of mixing ->list and ->lru. So, the new rule is: page->lru is what the you use if you want to keep your page on a list. Don't like the fact that it's not called ->list? Too bad.

commit 'slab: restrict the number of objects in a slab' uses __builtin_constant_p() on #if macro. It is wrong usage of builtin function, but it is compiled on x86 without any problem, so I can't find it before 0 day build system find it. This commit fixes the situation by using KMALLOC_MIN_SIZE, instead of KMALLOC_SHIFT_LOW. KMALLOC_SHIFT_LOW is parsed to ilog2() on some architecture and this ilog2() uses __builtin_constant_p() and results in the problem. This problem would disappear by using KMALLOC_MIN_SIZE, since it is just constant.

Now, the size of the freelist for the slab management diminish, so that the on-slab management structure can waste large space if the object of the slab is large. Consider a 128 byte sized slab. If on-slab is used, 31 objects can be in the slab. The size of the freelist for this case would be 31 bytes so that 97 bytes, that is, more than 75% of object size, are wasted. In a 64 byte sized slab case, no space is wasted if we use on-slab. So set off-slab determining constraint to 128 bytes.

Currently, the freelist of a slab consist of unsigned int sized indexes. Since most of slabs have less number of objects than 256, large sized indexes is needless. For example, consider the minimum kmalloc slab. It's object size is 32 byte and it would consist of one page, so 256 indexes through byte sized index are enough to contain all possible indexes. There can be some slabs whose object size is 8 byte. We cannot handle this case with byte sized index, so we need to restrict minimum object size. Since these slabs are not major, wasted memory from these slabs would be negligible. Some architectures' page size isn't 4096 bytes and rather larger than 4096 bytes (One example is 64KB page size on PPC or IA64) so that byte sized index doesn't fit to them. In this case, we will use two bytes sized index. Below is some number for this patch. * Before * kmalloc-512 525 640 512 8 1 : tunables 54 27 0 : slabdata 80 80 0 kmalloc-256 210 210 256 15 1 : tunables 120 60 0 : slabdata 14 14 0 kmalloc-192 1016 1040 192 20 1 : tunables 120 60 0 : slabdata 52 52 0 kmalloc-96 560 620 128 31 1 : tunables 120 60 0 : slabdata 20 20 0 kmalloc-64 2148 2280 64 60 1 : tunables 120 60 0 : slabdata 38 38 0 kmalloc-128 647 682 128 31 1 : tunables 120 60 0 : slabdata 22 22 0 kmalloc-32 11360 11413 32 113 1 : tunables 120 60 0 : slabdata 101 101 0 kmem_cache 197 200 192 20 1 : tunables 120 60 0 : slabdata 10 10 0 * After * kmalloc-512 521 648 512 8 1 : tunables 54 27 0 : slabdata 81 81 0 kmalloc-256 208 208 256 16 1 : tunables 120 60 0 : slabdata 13 13 0 kmalloc-192 1029 1029 192 21 1 : tunables 120 60 0 : slabdata 49 49 0 kmalloc-96 529 589 128 31 1 : tunables 120 60 0 : slabdata 19 19 0 kmalloc-64 2142 2142 64 63 1 : tunables 120 60 0 : slabdata 34 34 0 kmalloc-128 660 682 128 31 1 : tunables 120 60 0 : slabdata 22 22 0 kmalloc-32 11716 11780 32 124 1 : tunables 120 60 0 : slabdata 95 95 0 kmem_cache 197 210 192 21 1 : tunables 120 60 0 : slabdata 10 10 0 kmem_caches consisting of objects less than or equal to 256 byte have one or more objects than before.

To prepare to implement byte sized index for managing the freelist of a slab, we should restrict the number of objects in a slab to be less or equal to 256, since byte only represent 256 different values. Setting the size of object to value equal or more than newly introduced SLAB_OBJ_MIN_SIZE ensures that the number of objects in a slab is less or equal to 256 for a slab with 1 page. If page size is rather larger than 4096, above assumption would be wrong. In this case, we would fall back on 2 bytes sized index. If minimum size of kmalloc is less than 16, we use it as minimum object size and give up this optimization.

HPFS needs to load 4 consecutive 512-byte sectors when accessing the directory nodes or bitmaps. We can't switch to 2048-byte block size because files are allocated in the units of 512-byte sectors. Previously, the driver would allocate a 2048-byte area using kmalloc, copy the data from four buffers to this area and eventually copy them back if they were modified. In the current implementation of the buffer cache, buffers are allocated in the pagecache. That means that 4 consecutive 512-byte buffers are stored in consecutive areas in the kernel address space. So, we don't need to allocate extra memory and copy the content of the buffers there. This patch optimizes the code to avoid copying the buffers. It checks if the four buffers are stored in contiguous memory - if they are not, it falls back to allocating a 2048-byte area and copying data there.

Previously, hpfs scanned all bitmaps each time the user asked for free space using statfs. This patch changes it so that hpfs scans the bitmaps only once, remembes the free space and on next invocation of statfs it returns the value instantly. New versions of wine are hammering on the statfs syscall very heavily, making some games unplayable when they're stored on hpfs, with load times in minutes. This should be backported to the stable kernels because it fixes user-visible problem (excessive level load times in wine).

Revert commit ef83b078 "PCI: Remove from bus_list and release resources in pci_release_dev()" that made some nasty race conditions become possible. For example, if a Thunderbolt link is unplugged and then replugged immediately, the pci_release_dev() resulting from the hot-remove code path may be racing with the hot-add code path which after that commit causes various kinds of breakage to happen (up to and including a hard crash of the whole system). Moreover, the problem that commit ef83b078 attempted to address cannot happen any more after commit 8a4c5c32 "PCI: Check parent kobject in pci_destroy_dev()", because pci_destroy_dev() will now return immediately if it has already been executed for the given device.

Pull sound fixes from Takashi Iwai: "The big chunks here are the updates for oxygen driver for Xonar DG devices, which were slipped from the previous pull request. They are device-specific and thus not too dangerous. Other than that, all patches are small bug fixes, mainly for Samsung build fixes, a few HD-audio enhancements, and other misc ASoC fixes. (And this time ASoC merge is less than Octopus, lucky seven :)" * tag 'sound-fix-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (42 commits) ALSA: hda/hdmi - allow PIN_OUT to be dynamically enabled ALSA: hda - add headset mic detect quirks for another Dell laptop ALSA: oxygen: Xonar DG(X): cleanup and minor changes ALSA: oxygen: Xonar DG(X): modify high-pass filter control ALSA: oxygen: Xonar DG(X): modify input select functions ALSA: oxygen: Xonar DG(X): modify capture volume functions ALSA: oxygen: Xonar DG(X): use headphone volume control ALSA: oxygen: Xonar DG(X): modify playback output select ALSA: oxygen: Xonar DG(X): capture from I2S channel 1, not 2 ALSA: oxygen: Xonar DG(X): move the mixer code into another file ALSA: oxygen: modify CS4245 register dumping function ALSA: oxygen: modify adjust_dg_dac_routing function ALSA: oxygen: Xonar DG(X): modify DAC/ADC parameters function ALSA: oxygen: Xonar DG(X): modify initialization functions ALSA: oxygen: Xonar DG(X): add new CS4245 SPI functions ALSA: oxygen: additional definitions for the Xonar DG/DGX card ALSA: oxygen: change description of the xonar_dg.c file ALSA: oxygen: export oxygen_update_dac_routing symbol ALSA: oxygen: add mute mask for the OXYGEN_PLAY_ROUTING register ALSA: oxygen: modify the SPI writing function ...
