UBI: add lnum and vol_id to struct ubi_work 2012-05-21T08:34:41+00:00 Joel Reardon joel@clambassador.com 2012-05-18T13:40:24+00:00 d36e59e69b8be536c55d6118630f0221cee5ccee 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.
