Previous functionality\nis preserved when passing UBI_ALL for both values. The locations where ubi_wl_flush\nwere called are appropriately changed: ubi_leb_erase only flushes for the\nerased LEB, and ubi_create_volume forces only flushing for its volume id.\nExternal code can call this new feature via the new function ubi_flush() added\nto kapi.c, which simply passes through to ubi_wl_flush().\n\nThis was tested by disabling the call to do_work in ubi thread, which results\nin the work queue remaining unless explicitly called to remove. UBIFS was\nchanged to call ubifs_leb_change 50 times for four different LEBs. Then the\nnew function was called to clear the queue: passing wrong volume ids / lnum,\ncorrect ones, and finally UBI_ALL for both to ensure it was finally all\ncleard. The work queue was dumped each time and the selective removal\nof the particular LEB numbers was observed. Extra checks were enabled and\nubifs\u0027s integck was also run.

Then, as new bad\nblocks are marked over time, the OOB markers become incomplete and the\nflash-based table becomes the only source of current bad block\ninformation. This becomes an obvious problem when, for example:\n\n * bootloader cannot read the flash-based BBT format\n * BBT is corrupted and the flash must be rescanned for bad\n blocks; we want to remember bad blocks that were marked from Linux\n\nSo to keep the bad block markers in sync with the flash-based BBT, this\npatch changes the default so that we write bad block markers to the proper\nOOB area on each block in addition to flash-based BBT. Comments are\nupdated, expanded, and/or relocated as necessary.\n\nThe new flash-based BBT procedure for marking bad blocks:\n (1) erase the affected block, to allow OOB marker to be written cleanly\n (2) update in-memory BBT\n (3) write bad block marker to OOB area of affected block\n (4) update flash-based BBT\nNote that we retain the first error encountered in (3) or (4), finish the\nprocedures, and dump the error in the end.\n\nThis should handle power cuts gracefully enough. (1) and (2) are mostly\nharmless (note that (1) will not erase an already-recognized bad block).\nThe OOB and BBT may be \"out of sync\" if we experience power loss bewteen\n(3) and (4), but we can reasonably expect that on next boot, subsequent\nI/O operations will discover that the block should be marked bad again,\nthus re-syncing the OOB and BBT.\n\nNote that this is a change from the previous default flash-based BBT\nbehavior. If your system cannot support writing bad block markers to OOB,\nuse the new NAND_BBT_NO_OOB_BBM option (in combination with\nNAND_BBT_USE_FLASH and NAND_BBT_NO_OOB).\n\nSigned-off-by: Brian Norris \u003ccomputersforpeace@gmail.com\u003e\nSigned-off-by: Artem Bityutskiy \u003cartem.bityutskiy@linux.intel.com\u003e\nSigned-off-by: David Woodhouse \u003cDavid.Woodhouse@intel.com\u003e\n" }, { "commit": "3c3c10bba1e4ccb75b41442e45c1a072f6cded19", "tree": "5c929e46cd0b6fcf8a42db7637cf45dbf69fe126", "parents": [ "a6c22850d20273896e7c8ee996730ccf2ba60a22" ], "author": { "name": "Artem Bityutskiy", "email": "artem.bityutskiy@linux.intel.com", "time": "Mon Jan 30 14:58:32 2012 +0200" }, "committer": { "name": "David Woodhouse", "email": "David.Woodhouse@intel.com", "time": "Tue Mar 27 00:20:01 2012 +0100" }, "message": "mtd: add leading underscore to all mtd functions\n\nThis patch renames all MTD functions by adding a \"_\" prefix:\n\nmtd-\u003eerase -\u003e mtd-\u003e_erase\nmtd-\u003eread_oob -\u003e mtd-\u003e_read_oob\n...\n\nThe reason is that we are re-working the MTD API and from now on it is\nan error to use MTD function pointers directly - we have a corresponding\nAPI call for every pointer.

UBI needs\nthis information because it affects how it handles the underlying flash.\nE.g., if the underlying flash is NOR, it cannot have bad blocks and any\nwrite or erase error is fatal, and all we can do is to switch to R/O\nmode. We do not need to reserve a pool of good eraseblocks for bad\neraseblocks handling, and so on.\n\nThis patch also removes \u0027mtd_can_have_bb()\u0027 invocations from Logfs to\nensure correct Logfs behavior.\n\nI\u0027ve tested that with this patch UBI works on top of NOR and NAND\nflashes emulated by mtdram and nandsim correspondingly.\n\nThis patch is based on patch from Linus Torvalds.\n\nSigned-off-by: Artem Bityutskiy \u003cartem.bityutskiy@linux.intel.com\u003e\nAcked-by: Jörn Engel \u003cjoern@logfs.org\u003e\nAcked-by: Prasad Joshi \u003cprasadjoshi.linux@gmail.com\u003e\nAcked-by: Brian Norris \u003ccomputersforpeace@gmail.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d3712b9dfcf44ca145cf87e7f4096fa2d923471a", "tree": "d72aaaa845fb81c669093363a0a1cc6d9e96baf2", "parents": [ "c5d2bc11030568966f04a2af35bacf33d3e37af7", "f2933e86ad93a8d1287079d59e67afd6f4166a9d" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 31 09:23:59 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 31 09:23:59 2012 -0800" }, "message": "Merge tag \u0027for-linus\u0027 of git://github.com/prasad-joshi/logfs_upstream\n\nThere are few important bug fixes for LogFS\n\n* tag \u0027for-linus\u0027 of git://github.com/prasad-joshi/logfs_upstream:\n Logfs: Allow NULL block_isbad() methods\n logfs: Grow inode in delete path\n logfs: Free areas before calling generic_shutdown_super()\n logfs: remove useless BUG_ON\n MAINTAINERS: Add Prasad Joshi in LogFS maintiners\n logfs: Propagate page parameter to __logfs_write_inode\n logfs: set superblock shutdown flag after generic sb shutdown\n logfs: take write mutex lock during fsync and sync\n logfs: Prevent memory corruption\n logfs: update page reference count for pined pages\n\nFix up conflict in fs/logfs/dev_mtd.c due to semantic change in what\n\"mtd-\u003eblock_isbad\" means in commit f2933e86ad93: \"Logfs: Allow NULL\nblock_isbad() methods\" clashing with the abstraction changes in the\ncommits 7086c19d0742: \"mtd: introduce mtd_block_isbad interface\" and\nd58b27ed58a3: \"logfs: do not use \u0027mtd-\u003eblock_isbad\u0027 directly\".\n\nThis resolution takes the semantics from commit f2933e86ad93, and just\nmakes mtd_block_isbad() return zero (false) if the \u0027block_isbad\u0027\nfunction is NULL.
