treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

mtd: ubi: Remove unused ubi_flush

2025-07-24T20:19:17+00:00

ubi_flush() was added in 2012 as part of commit 62f384552b67 ("UBI: modify ubi_wl_flush function to clear work queue for a lnum") but has remained unused. (It's friend ubi_wl_flush() is still used) Remove it. Signed-off-by: Dr. David Alan Gilbert Signed-off-by: Richard Weinberger

mtd: ubi: introduce pre-removal notification for UBI volumes

2024-02-25T21:41:33+00:00

Introduce a new notification type UBI_VOLUME_SHUTDOWN to inform users that a volume is just about to be removed. This is needed because users (such as the NVMEM subsystem) expect that at the time their removal function is called, the parenting device is still available (for removal of sysfs nodes, for example, in case of NVMEM which otherwise WARNs on volume removal).

mtd: ubi: block: use notifier to create ubiblock from parameter

2024-02-25T21:41:32+00:00

Use UBI_VOLUME_ADDED notification to create ubiblock device specified on kernel cmdline or module parameter. This makes thing more simple and has the advantage that ubiblock devices on volumes which are not present at the time the ubi module is probed will still be created.

mtd: ubi: block: wire-up device parent

2023-02-13T21:24:10+00:00

ubiblock devices were previously only identifyable by their name, but not connected to their parent UBI volume device e.g. in sysfs. Properly parent ubiblock device as descendant of a UBI volume device to reflect device model hierachy. Signed-off-by: Daniel Golle Signed-off-by: Richard Weinberger

ubi: Do not drop UBI device reference before using

2018-12-13T21:09:44+00:00

The UBI device reference is dropped but then the device is used as a parameter of ubi_err. The bug is introduced in changing ubi_err's behavior. The old ubi_err does not require a UBI device as its first parameter, but the new one does.

ubi: provide a way to skip CRC checks

2018-08-14T22:25:20+00:00

Some users of static UBI volumes implement their own integrity check, thus making the volume CRC check done at open time useless. For instance, this is the case when one use the ubiblock + dm-verity + squashfs combination, where dm-verity already checks integrity of the block device but this time at the block granularity instead of verifying the whole volume. Skipping this test drastically improves the boot-time.
