UBI: clean-up printing helpers

2015-01-28T15:09:17Z

Let's prefix UBI messages with 'ubiX' instead of 'UBI-X' - this is more consistent with the way we name UBI devices. Also, commit "32608703 UBI: Extend UBI layer debug/messaging capabilities" added the function name print to 'ubi_msg()' - lets revert this change, since these messages are supposed to be just informative messages, and not debugging messages.

UBI: Add initial support for scatter gather

2015-01-28T15:04:26Z

Adds a new set of functions to deal with scatter gather. ubi_eba_read_leb_sg() will read from a LEB into a scatter gather list. The new data structure struct ubi_sgl will be used within UBI to hold the scatter gather list itself and metadata to have a cursor within the list.

UBI: Implement UBI_METAONLY

2015-01-28T14:57:04Z

UBI_METAONLY is a new open mode for UBI volumes, it indicates that only meta data is being changed. Meta data in terms of UBI volumes means data which is stored in the UBI volume table but not on the volume itself. While it does not interfere with UBI_READONLY and UBI_READWRITE it is not allowed to use UBI_METAONLY together with UBI_EXCLUSIVE.

UBI: Extend UBI layer debug/messaging capabilities

2014-11-07T10:08:51Z

If there is more then one UBI device mounted, there is no way to distinguish between messages from different UBI devices. Add device number to all ubi layer message types. The R/O block driver messages were replaced by pr_* since ubi_device structure is not used by it. Amended a bit by Artem. Signed-off-by: Tanya Brokhman Signed-off-by: Artem Bityutskiy

UBI: wl: Rename cancel flag to shutdown

2014-09-26T10:43:32Z

It confused me more than once that the cancel flag of the work function does not indicate the cancellation of a single work. In fact it indicates the WL sub-system shutdown and therefore worker functions have to free their wl_entries too. That's why you cannot cancel a single work, you can only shutdown all works.

mtd: delete non-required instances of include

2014-03-11T05:42:22Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

UBI: block: Use ENOSYS as return value when CONFIG_UBIBLOCK=n

2014-03-05T13:48:35Z

In order to have a way of distinguishing an invalid ioctl from a not supported (but otherwise valid) ioctl, this commit changes the return value of the ioctl stubs from ENOTTY to ENOSYS. This will be useful to report more accurate error messages from userspace tools. Signed-off-by: Ezequiel Garcia Signed-off-by: Artem Bityutskiy

UBI: block: do not use term "attach"

2014-03-04T11:52:33Z

We already use term attach/detach for UBI->MTD relations, let's not use this for UBI->ubiblock relations to avoid confusion. Just use 'create' and 'remove' instead. E.g., "create a R/O block device on top of a UBI volume". Signed-off-by: Artem Bityutskiy
