mtd: ubi: Fix worker handling

2018-02-19T07:22:58Z

Fixes a bug found on thuban boards, which were for 2 years in a long-term test with varying temperatures. They showed problems in u-boot when attaching the ubi partition: U-Boot# run flash_self_test Booting from nand set A...

Reason is, that accidentially the U-Boot implementation from __schedule_ubi_work() did not check the flag ubi->thread_enabled and started with wearleveling work, but ubi did not have setup all structures at this point and crashes. Solve this problem by splitting work scheduling and processing. Signed-off-by: Richard Weinberger Signed-off-by: Heiko Schocher

ubi: Ensure no fastmap flush after uif_close

2018-02-06T06:05:57Z

On detach UBI attempts to update fastmap after closing user interfaces but at this point UBI volumes have already been free()'ed and fastmap can no longer access these data structures. Signed-off-by: Martin Townsend Cc: hs@denx.de Cc: kmpark@infradead.org Cc: richard@sigma-star.at

ubi: no NULL check needed before kmem_cache_destroy

kmem_cache_destroy calls free which checks for NULL. Problem was indicated by coccinelle. Signed-off-by: Heinrich Schuchardt

ubi: Kconfig: Make MTD_UBI select MTD_PARTITIONS

2017-07-24T11:33:34Z

This missing dependency has probably remained under the radar because MTD_PARTITIONS is still whitelisted. Signed-off-by: Karl Beldan Reviewed-by: Tom Rini

mtd, ubi: set free_count to zero before walking through erase list

2016-04-22T09:47:37Z

Set free_count to zero before walking through ai->erase list in wl_init(). As U-Boot has no workqueue/threads, it immediately calls erase_worker(), which increase for each erased block free_count. Without this patch, free_count gets after this initialized to zero in wl_init(), so the free_count variable always has the maybe wrong value 0. Detected this behaviour on the dxr2 board, where the UBI fastmap gets not written when attaching/dettaching on an empty NAND. It drops instead the error message: could not find any anchor PEB With this patch, fastmap gets written on dettach. Signed-off-by: Heiko Schocher Reviewed-by: Boris Brezillon

bug.h: move BUILD_BUG_* defines to include/linux/bug.h

2016-01-25T15:39:59Z

BUILD_BUG_* macros have been defined in several headers. It would be nice to collect them in include/linux/bug.h like Linux. This commit is cherry-picking useful macros from include/linux/bug.h of Linux 4.4. I did not import BUILD_BUG_ON_MSG() because it would not work if it is used with include/common.h in U-Boot. I'd like to postpone it until the root cause (the "error()" macro in include/common.h causes the name conflict with "__attribute__((error()))") is fixed.
