For this driver, there is nothing between nand_scan_ident() and nand_scan_tail(). They can be merged into nand_scan(). Also, nand_scan() returns an appropriate error value when it fails. Use it instead of the fixed error code -ENXIO.

If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module.

Usually Fastmap is free to consider every PEB in one of the pools as newer than the existing PEB. Since PEBs in a pool are by definition newer than everything else. But update_vol() missed the case that a pool can contain more than one candidate.

When writing a new Fastmap the first thing that happens is refilling the pools in memory. At this stage it is possible that new PEBs from the new pools get already claimed and written with data. If this happens before the new Fastmap data structure hits the flash and we face power cut the freshly written PEB will not scanned and unnoticed. Solve the issue by locking the pools until Fastmap is written. Cc: <stable@vger.kernel.org> Fixes: dbb7d2a8 ("UBI: Add fastmap core") Signed-off-by: NRichard Weinberger <richard@nod.at>

When Fastmap is used we can face here an -EBADMSG since Fastmap cannot know about unmaps. If the erasure was interrupted the PEB may show ECC errors and UBI would go to ro-mode as it assumes that the PEB was check during attach time, which is not the case with Fastmap.
