In addition, eMMC v4.4\ncards can support secure erase, trim and secure trim operations that are\nall variants of the basic erase command.\n\nSD/MMC device attributes \"erase_size\" and \"preferred_erase_size\" have been\nadded.\n\n\"erase_size\" is the minimum size, in bytes, of an erase operation. For\nMMC, \"erase_size\" is the erase group size reported by the card. Note that\n\"erase_size\" does not apply to trim or secure trim operations where the\nminimum size is always one 512 byte sector. For SD, \"erase_size\" is 512\nif the card is block-addressed, 0 otherwise.\n\nSD/MMC cards can erase an arbitrarily large area up to and\nincluding the whole card. When erasing a large area it may\nbe desirable to do it in smaller chunks for three reasons:\n\n 1. A single erase command will make all other I/O on the card\n wait. This is not a problem if the whole card is being erased, but\n erasing one partition will make I/O for another partition on the\n same card wait for the duration of the erase - which could be a\n several minutes.\n\n 2. To be able to inform the user of erase progress.\n\n 3. The erase timeout becomes too large to be very useful.\n Because the erase timeout contains a margin which is multiplied by\n the size of the erase area, the value can end up being several\n minutes for large areas.\n\n\"erase_size\" is not the most efficient unit to erase (especially for SD\nwhere it is just one sector), hence \"preferred_erase_size\" provides a good\nchunk size for erasing large areas.\n\nFor MMC, \"preferred_erase_size\" is the high-capacity erase size if a card\nspecifies one, otherwise it is based on the capacity of the card.\n\nFor SD, \"preferred_erase_size\" is the allocation unit size specified by\nthe card.\n\n\"preferred_erase_size\" is in bytes.\n\nSigned-off-by: Adrian Hunter \u003cadrian.hunter@nokia.com\u003e\nAcked-by: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: Kyungmin Park \u003ckmpark@infradead.org\u003e\nCc: Madhusudhan Chikkature \u003cmadhu.cr@ti.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Ben Gardiner \u003cbengardiner@nanometrics.ca\u003e\nCc: \u003clinux-mmc@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "81d73a32d775ae9674ea6edf0b5b721fc3bc57d9", "tree": "c4097c3c7715a128cf54252b2ff906d3d8946ae0", "parents": [ "a50aeb40144982eb766053309b6fc33e14ca46f0" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Wed Aug 11 14:17:44 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Aug 12 08:43:30 2010 -0700" }, "message": "mm: fix writeback_in_progress()\n\nCommit 83ba7b071f3 (\"writeback: simplify the write back thread queue\")\nbroke writeback_in_progress() as in that commit we started to remove work\nitems from the list at the moment we start working on them and not at the\nmoment they are finished.

So i decided to write the API as a set of macros, which\nis the only way to do a kind of template meta programming without C++.\nThis macros handles the different types of fifos in a transparent way.\n\nThere are a lot of benefits:\n\n- Compile time handling of the different fifo types\n- Better performance (a save put or get of an integer does only generate\n 9 assembly instructions on a x86)\n- Type save\n- Cleaner interface, the additional kfifo_..._rec() functions are gone\n- Easier to use\n- Less error prone\n- Different types of fifos: it is now possible to define a int fifo or\n any other type. See below for an example.\n- Smaller footprint for none byte type fifos\n- No need of creating a second hidden variable, like in the old DEFINE_KFIFO\n\nThe API was not changed.\n\nThere are now real in place fifos where the data space is a part of the\nstructure. The fifo needs now 20 byte plus the fifo space. Dynamic\nassigned or allocated create a little bit more code.\n\nMost of the macros code will be optimized away and simple generate a\nfunction call. Only the really small one generates inline code.\n\nAdditionally you can now create fifos for any data type, not only the\n\"unsigned char\" byte streamed fifos.\n\nThere is also a new kfifo_put and kfifo_get function, to handle a single\nelement in a fifo. This macros generates inline code, which is lit bit\nlarger but faster.\n\nI know that this kind of macros are very sophisticated and not easy to\nmaintain. But i have all tested and it works as expected. I analyzed the\noutput of the compiler and for the x86 the code is as good as hand written\nassembler code. For the byte stream fifo the generate code is exact the\nsame as with the current kfifo implementation. For all other types of\nfifos the code is smaller before, because the interface is easier to use.\n\nThe main goal was to provide an API which is very intuitive, save and easy\nto use. So linux will get now a powerful fifo API which provides all what\na developer needs. This will save in the future a lot of kernel space,\nsince there is no need to write an own implementation. Most of the device\ndriver developers need a fifo, and also deep kernel development will gain\nbenefit from this API.\n\nHere are the results of the text section usage:\n\nExample 1:\n kfifo_put/_get kfifo_in/out current kfifo\ndynamic allocated 0x000002a8 0x00000291 0x00000299\nin place 0x00000291 0x0000026e 0x00000273\n\nkfifo.c new old\ntext section size 0x00000be5 0x000008b2\n\nAs you can see, kfifo_put/kfifo_get creates a little bit more code than\nkfifo_in/kfifo_out, but it is much faster (the code is inline).\n\nThe code is complete hand crafted and optimized. The text section size is\nas small as possible. You get all the fifo handling in only 3 kb. This\nincludes type safe fix size records, dynamic records and DMA handling.\n\nThis should be the final version. All requested features are implemented.\n\nNote: Most features of this API doesn\u0027t have any users. All functions\nwhich are not used in the next 9 months will be removed. So, please adapt\nyour drivers and other sources as soon as possible to the new API and post\nit.\n\nThis are the features which are currently not used in the kernel:\n\nkfifo_to_user()\nkfifo_from_user()\nkfifo_dma_....() macros\nkfifo_esize()\nkfifo_recsize()\nkfifo_put()\nkfifo_get()\n\nThe fixed size record elements, exclude \"unsigned char\" fifo\u0027s and the\nvariable size records fifo\u0027s\n\nThis patch:\n\nUser of the kernel fifo should never bypass the API and directly access\nthe fifo structure. Otherwise it will be very hard to maintain the API.\n\nSigned-off-by: Stefani Seibold \u003cstefani@seibold.net\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ad9c7ed0685406fe3cd7f0749b82bf433a39dd9c", "tree": "82c4c11b94e10b71fc0796f6a4bfb9ed1e0115be", "parents": [ "ab654bab04be435a9671e0dcf49c18f9782dd838" ], "author": { "name": "Robert P.

And the reference count is kept until the page is\nuncharged. But this has 2 bad effect.\n\n 1. Because css_get/put calls atomic_inc()/dec, heavy call of them\n on large smp will not scale well.\n 2. Because css\u0027s refcnt cannot be in a state as \"ready-to-release\",\n cgroup\u0027s notify_on_release handler can\u0027t work with memcg.\n 3. css\u0027s refcnt is atomic_t, it means smaller than 32bit. Maybe too small.\n\nThis has been a problem since the 1st merge of memcg.\n\nThis is a trial to remove css\u0027s refcnt per a page. Even if we remove\nrefcnt, pre_destroy() does enough synchronization as\n - check res-\u003eusage \u003d\u003d 0.\n - check no pages on LRU.\n\nThis patch removes css\u0027s refcnt per page.
