* UBI: correct ubi_wl_flush lockingArtem Bityutskiy2012-06-071-4/+13
| | | | | | | | | | | Commit "62f38455 UBI: modify ubi_wl_flush function to clear work queue for a lnum" takes the 'work_sem' semaphore in write mode for the entire loop, which is not very good because it will block other workers for potentially long time. We do not need to have it in write mode - read mode is enough, and we do not need to hole it over the entire loop. So this patch turns changes the locking: takes 'work_sem' in read mode and pushes it down to the loop. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
* UBI: fix debugfs-less systems supportArtem Bityutskiy2012-06-071-2/+10
| | | | | | | | | | | Commit "aa44d1d UBI: remove Kconfig debugging option" broke UBI and it refuses to initialize if debugfs (CONFIG_DEBUG_FS) is disabled. I incorrectly assumed that debugfs files creation function will return success if debugfs is disabled, but they actually return -ENODEV. This patch fixes the issue.

* UBI: modify ubi_wl_flush function to clear work queue for a lnumJoel Reardon2012-05-216-31/+69
| | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies ubi_wl_flush to force the erasure of particular volume id / logical eraseblock number pairs. Previous functionality is preserved when passing UBI_ALL for both values. The locations where ubi_wl_flush were called are appropriately changed: ubi_leb_erase only flushes for the erased LEB, and ubi_create_volume forces only flushing for its volume id. External code can call this new feature via the new function ubi_flush() added to kapi.c, which simply passes through to ubi_wl_flush(). This was tested by disabling the call to do_work in ubi thread, which results in the work queue remaining unless explicitly called to remove. UBIFS was changed to call ubifs_leb_change 50 times for four different LEBs. Then the new function was called to clear the queue: passing wrong volume ids / lnum, correct ones, and finally UBI_ALL for both to ensure it was finally all cleard. The work queue was dumped each time and the selective removal of the particular LEB numbers was observed. Extra checks were enabled and ubifs's integck was also run. Finally, the drive was repeatedly filled and emptied to ensure that the queue was cleared normally. Artem: amended the patch.

* UBI: add lnum and vol_id to struct ubi_workJoel Reardon2012-05-213-18/+33
| | | | | | | | | | | | | | | | | | | | | This is part of a multipart patch to allow UBI to force the erasure of particular logical eraseblock numbers. In this patch, the volume id and LEB number are added to ubi_work data structure, and both are also passed as a parameter to schedule erase to set it appropriately. Whenever ubi_wl_put_peb is called, the lnum is also passed to be forwarded to schedule erase. Later, a new ubi_sync_lnum will be added to execute immediately all work related to that lnum. This was tested by outputting the vol_id and lnum during the schedule of erasure. The ubi thread was disabled and two ubifs drives on separate partitions repeated changed a small number of LEBs. The ubi module was readded, and all the erased LEBs, corresponding to the volumes, were added to the schedule erase queue.

* UBI: add volume id struct ubi_ainf_pebJoel Reardon2012-05-212-16/+35
| | | | | | | | | | | | | | | | This patch adds the volume id to struct ubi_ainf_peb when scanning the LEBs at startup. PEBs now added to the erase queue will know their original LEB number and volume id, if available, and will be -1 otherwise (for instance, if the VID header is unreadable). This was tested by creating an ubi device with 3 volumes and disabiling the ubi_thread's do_work functionality. The different ubi volumes were formatted to ubifs and had files created and erased. The ubi modules was reloaded and the list of LEB's added to the erased list was outputted, confirming the volume ids and LEB numbers were appropriate.
