* UBIFS: clean-up commentariesArtem Bityutskiy2011-03-16
| | | | | | | Clean-up commentaries in debug.h and remove references to non-existing symblols. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: save 128KiB or more RAMArtem Bityutskiy2011-03-16
| | | | | | | | When debugging is enabled, we allocate a buffer of PEB size for various debugging purposes. However, now all users of this buffer are gone and we can safely remove it and save 128KiB or more RAM. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: simplify UBIFS Kconfig menuArtem Bityutskiy2011-03-11
| | | | | | | | | Remove debug message level and debug checks Kconfig options as they proved to be useless anyway. We have sysfs interface which we can use for fine-grained debugging messages and checks selection, see Documentation/filesystems/ubifs.txt for mode details.

* UBIFS: introduce list sorting debugging checksArtem Bityutskiy2010-08-30
| | | | | | | | | | | | | | | The UBIFS bug in the GC list sorting comparison functions inspired me to write internal debugging check functions which verify that the list of nodes is sorted properly. So, this patch implements 2 new debugging functions: o 'dbg_check_data_nodes_order()' - check order of data nodes list o 'dbg_check_nondata_nodes_order()' - check order of non-data nodes list The debugging functions are executed only if general UBIFS debugging checks are enabled. And they are compiled out if UBIFS debugging is disabled. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: improve journal head debugging printsArtem Bityutskiy2009-09-15
| | | | | | | Convert the journal head integer into the head name when printing debugging information. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: add inode size debugging checkArtem Bityutskiy2009-09-10
| | | | | | | | | Add one more check to UBIFS - a check that makes sure that there are no data nodes beyond inode size. And few commantaries fixes along the line. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Reviewed-by: Adrian Hunter <Adrian.Hunter@nokia.com>
* UBIFS: add re-mount debugging checksArtem Bityutskiy2009-01-26
| | | | | | | We observe space corrupted accounting when re-mounting. So add some debbugging checks to catch problems like this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: introduce LPT dump functionArtem Bityutskiy2008-12-03

* UBIFS: add debugfs supportArtem Bityutskiy2008-12-03
| | | | | | | | We need to have a possibility to see various UBIFS variables and ask UBIFS to dump various information. Debugfs is what we need. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: separate debugging fields outArtem Bityutskiy2008-12-03
| | | | | | | | Introduce a new data structure which contains all debugging stuff inside. This is cleaner than having debugging stuff directly in 'c'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: add more debugging messages for LPTAdrian Hunter2008-09-30
| | | | | | | Also add debugging checks for LPT size and separate out c->check_lpt_free from unrelated bitfields. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>
* UBIFS: improve arguments checking in debugging messagesArtem Bityutskiy2008-08-13
| | | | | | | | | | Use "if (0) printk()" construct in debugging print macros to make the debugging messages be checked even if debugging is off. This patch also removes some unneeded spaces and blank lines. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: add new flash file systemArtem Bityutskiy2008-07-15
