* mtd: nand: move NAND_CREATE_EMPTY_BBT flagBrian Norris2011-09-111-1/+1
| | | | | | | | | | | | | | | The NAND_CREATE_EMPTY_BBT flag was added by commit: 453281a973c10bce941b240d1c654d536623b16b mtd: nand: introduce NAND_CREATE_EMPTY_BBT This flag is not used within the kernel and not explained well, so I took the liberty to edit its comments. Also, this is a BBT-related flag (and closely tied with NAND_BBT_CREATE) so I'm moving it to bbm.h next to NAND_BBT_CREATE, thus requiring that we use the flag in nand_chip.bbt_options, *not* in nand_chip.options.

* mtd: nand: rename NAND_USE_FLASH_BBTBrian Norris2011-09-1116-22/+22
| | | | | | | | | | | | | | | Recall the recently added prefix requirements: * "NAND_" for flags in nand.h, used in nand_chip.options * "NAND_BBT_" for flags in bbm.h, used in nand_chip.bbt_options or in nand_bbt_descr.options Thus, I am changing NAND_USE_FLASH_BBT to NAND_BBT_USE_FLASH. Again, this flag is found in bbm.h and so should NOT be used in the "nand_chip.options" field.

* mtd: nand: consolidate redundant flash-based BBT flagsBrian Norris2011-09-1117-29/+39
| | | | | | | | | | | | | | | | | | | | | | | | | This patch works with the following three flags from two headers (nand.h and bbm.h): (1) NAND_USE_FLASH_BBT (nand.h) (2) NAND_USE_FLASH_BBT_NO_OOB (nand.h) (3) NAND_BBT_NO_OOB (bbm.h) These flags are all related and interdependent, yet they were in different headers. Flag (2) is simply the combination of (1) and (3) and can be eliminated. This patch accomplishes the following: * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2)) * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h It's important to note that because (1) and (3) are now both found in bbm.h, they should NOT be used in the "nand_chip.options" field. I removed a small section from the mtdnand DocBook because it referes to NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.

* mtd: nand: separate chip options / bbt_optionsBrian Norris2011-09-112-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch handles the problems we've been having with using conflicting flags from nand.h and bbm.h in the same nand_chip.options field. We should try to separate these two spaces a little more clearly, and so I have added a bbt_options field to nand_chip. Important notes about nand_chip fields: * bbt_options field should contain ONLY flags from bbm.h. They should be able to pass safely to a nand_bbt_descr data structure. - BBT option flags start with the "NAND_BBT_" prefix. * options field should contian ONLY flags from nand.h. Ideally, they should not be involved in any BBT related options. - NAND chip option flags start with the "NAND_" prefix. * Every flag should have a nice comment explaining what the flag is. While this is not yet the case on all existing flags, please be sure to write one for new flags. Even better, you can help document the code better yourself! Please try to follow these conventions to make everyone's lives easier. Among the flags that are being moved to the new bbt_options field throughout various drivers, etc. are: * NAND_BBT_SCANLASTPAGE * NAND_BBT_SCAN2NDPAGE and there will be more to come.

* mtd: nand: remove NAND_BBT_SCANBYTE1AND6 optionBrian Norris2011-09-112-50/+6
| | | | | | | | | | | | | | | | | | | | This patch reverts most of: commit 58373ff0afff4cc8ac40608872995f4d87eb72ec mtd: nand: more BB Detection refactoring and dynamic scan options According to the discussion at: http://lists.infradead.org/pipermail/linux-mtd/2011-May/035696.html the NAND_BBT_SCANBYTE1AND6 flag, although technically valid, can break some existing ECC layouts that use the 6th byte in the OOB for ECC data. Furthermore, we apparently do not need to scan both bytes 1 and 6 in the OOB region of the devices under consideration; instead, we only need to scan one or the other. Thus, the NAND_BBT_SCANBYTE1AND6 flag is at best unnecessary and at worst a regression.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a number of file systems that don't have a mount point (e.g. sockfs and pipefs), they are not marked as long term. Therefore in mntput_no_expire, all locks in vfs_mount lock are taken instead of just local cpu's lock to aggregate reference counts when we release reference to file objects. In fact, only local lock need to have been taken to update ref counts as these file systems are in no danger of going away until we are ready to unregister them. The attached patch marks file systems using kern_mount without mount point as long term. The contentions of vfs_mount lock is now eliminated. Before un-registering such file system, kern_unmount should be called to remove the long term flag and make the mount point ready to be freed.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an oops in the error path of 'ubi_attach_mtd_dev()'. If anything after 'uif_init()' fails, we get an oops in 'cancel_pending()'. The reason is that 'uif_close()' drops the last reference count for 'ubi->dev' and whole 'struct ubi_device' is freed. And then 'ubi_wl_close()'->'cancel_pending()' tries to access the 'ubi' pointer and problems begin. Note, in 'ubi_detach_mtd_dev()' function we get a device reference to work-around this issue. Do the same in the error path of 'ubi_attach_mtd_dev()'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | UBI: switch debugging tests knobs to debugfsArtem Bityutskiy2011-06-012-28/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | Kill the UBI 'debug_tsts' module parameter and switch to debugfs. Create per-test mode files there. E.g., to enable bit-flips emulation you may just do: echo 1 > /sys/kernel/debug/ubi/ubi0/tst_emulate_bitflips Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | UBI: make it possible to use struct ubi_device in debug.hArtem Bityutskiy2011-06-012-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current layout does not allow us to add inline functions to debug.h which use the 'struct ubi_device' object, because it is undefined there. Move '#include "debug.h"' in "ubi.h" down so to make 'struct ubi_device" be defined. Additionally, this makes it possible to remove a bunch of forward declarations in "debug.h". This is a preparation to the next patch. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | UBI: prepare debugging stuff to further debugfs conversionArtem Bityutskiy2011-06-013-13/+20
| | | | | | | | | | | | | | | | | | | | | | | | We'll need the 'struct ubi_device *ubi' pointer in every debugging function (to access the ->dbg field), so add this pointer to all the functions implementing UBI debugging test modes like 'ubi_dbg_is_bitflip()' etc. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | UBI: use debugfs for the extra checks knobsArtem Bityutskiy2011-06-019-36/+310
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces debugfs support to UBI. All the UBI stuff is kept in the "ubi" debugfs directory, which contains per-UBI device "ubi/ubiX" sub-directories, containing debugging files. This file also creates "ubi/ubiX/chk_gen" and "ubi/ubiX/chk_io" knobs for switching general and I/O extra checks on and off. And it removes the 'debug_chks' UBI module parameters.

| |/ | | | | | | | | | | | | | | | | | | | | This is a minor preparational patch which changes the 'paranoid_check_in_wl_tree()' function interface by adding the 'ubi' parameter which will be needed there in the next patch. And while on it, add "const" qualifier to the 'ubi' parameter of the 'paranoid_check_in_pq()' function. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
