* UBIFS: amend ubifs_recover_leb interfaceArtem Bityutskiy2011-06-011-1/+1
| | | | | | | | | | | Instead of passing "grouped" parameter to 'ubifs_recover_leb()' which tells whether the nodes are grouped in the LEB to recover, pass the journal head number and let 'ubifs_recover_leb()' look at the journal head's 'grouped' flag. This patch is a preparation to a further fix where we'll need to know the journal head number for other purposes. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: fix minor stylistic issuesArtem Bityutskiy2011-05-131-1/+2
| | | | | | | | | Fix several minor stylistic issues: * lines longer than 80 characters * space before closing parenthesis ')' * spaces in the indentations Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: use GFP_NOFS properlyArtem Bityutskiy2011-03-241-1/+1
| | | | | | | | | This patch fixes a brown-paperbag bug which was introduced by me: I used incorrect "GFP_KERNEL | GFP_NOFS" allocation flags to make sure my allocations do not cause write-back. But the correct form is "GFP_NOFS". Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: allocate orphans scan buffer on demandArtem Bityutskiy2011-03-161-1/+9
| | | | | | | | | | | Instead of using pre-allocated 'c->dbg->buf' buffer in 'dbg_scan_orphans()', dynamically allocate it when needed. The intend is to get rid of the pre-allocated 'c->dbg->buf' buffer and save 128KiB of RAM (or more if PEB size is larger). Indeed, currently we allocate this memory even if the user never enables any self-check, which is wasteful. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: check ubifs_scan error codes betterArtem Bityutskiy2009-09-101-1/+2
| | | | | | | | | | | The 'ubifs_scan()' function returns -EUCLEAN if something is corrupted and recovery is needed, otherwise it returns other error codes. However, in few places UBIFS does not check the error codes and runs recovery. This patch changes this behavior and makes UBIFS start recovery only on -EUCLEAN errors.

* UBIFS: do not print scary error messages needlesslyArtem Bityutskiy2009-09-101-2/+2
| | | | | | | | | | | | | | | | At the moment UBIFS print large and scary error messages and flash dumps in case of nearly any corruption, even if it is a recoverable corruption. For example, if the master node is corrupted, ubifs_scan() prints error dumps, then UBIFS recovers just fine and goes on. This patch makes UBIFS print scary error messages only in real cases, which are not recoverable. It adds 'quiet' argument to the 'ubifs_scan()' function, so the caller may ask 'ubi_scan()' not to print error messages if the caller is able to do recovery.

* UBIFS: ensure orphan area head is initializedAdrian Hunter2009-01-261-19/+19
| | | | | | | | | | | When mounting read-only the orphan area head is not initialized. It must be initialized when remounting read/write, but it was not. This patch fixes that.

* UBIFS: separate debugging fields outArtem Bityutskiy2008-12-031-1/+1
| | | | | | | | 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: fix compilation warningsArtem Bityutskiy2008-11-061-12/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We print 'ino_t' type using '%lu' printk() placeholder, but this results in many warnings when compiling for Alpha platform. Fix this by adding (unsingned long) casts.
