Fix checkpatch.pl errors and warnings: * space before tab * line over 80 characters * include linux/ioctl.h instead of asm/ioctl.h Signed-off-by: Artem Bityutskiy

UBI: use packed instead of attribute__((packed))

2011-04-14T08:34:41Z

There was an attempt to standartize various "__attribute__" and other macros in order to have potentially portable and more consistent code, see commit 82ddcb040570411fc2d421d96b3e69711c670328. Note, that commit refers Rober Love's blog post, but the URL is broken, the valid URL is: http://blog.rlove.org/2005/10/with-little-help-from-your-compiler.html Moreover, nowadays checkpatch.pl warns about using __attribute__((packed)): "WARNING: __packed is preferred over __attribute__((packed))" It is not a big deal for UBI to use __packed, so let's do it.

UBI: re-name set volume properties ioctl

2011-04-14T08:34:40Z

Rename the ioctl which sets volume properties from 'UBI_IOCSETPROP' to 'UBI_IOCSETVOLPROP' to reflect the fact that this ioctl is about volume properties, not device properties. This is also consistent with the other volume ioctl name - 'UBI_IOCVOLUP'. The main motivation for the re-name, however, is that we are going to introduce the per-UBI device "set properties" ioctl, so we need good and logical naming. At the same time, re-name the "set volume properties request" data structure from 'struct ubi_set_prop_req' to 'struct ubi_set_vol_prop_req'. And re-name 'UBI_PROP_DIRECT_WRITE' to 'UBI_VOL_PROP_DIRECT_WRITE'. Signed-off-by: Artem Bityutskiy

mtd: Define MLC Flash as a different flash type

2010-10-24T23:50:20Z

MLC NAND Flash has a different cell structure and differs in functioning than the SLC NAND Flash. Hence we are considering it as a different Flash type. Signed-off-by: Rohit H.S Signed-off-by: Raghav Gupta Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: edit comments on deprecation of ioctl ECCGETLAYOUT

2010-10-24T22:37:27Z

There were some improvements and additions necessary in the comments explaining of the expansion of nand_ecclayout, the introduction of nand_ecclayout_user, and the deprecation of the ioctl ECCGETLAYOUT. Also, I found a better placement for the macro MTD_MAX_ECCPOS_ENTRIES; next to the definition of MTD_MAX_OOBFREE_ENTRIES in mtd-abi.h. The macro is really only important for the ioctl code (found in drivers/mtd/mtdchar.c) but since there are small edits being made to the user-space header, I figured this is a better location.

mtd: nand: expand nand_ecc_layout, deprecate ioctl ECCGETLAYOUT

2010-10-24T22:37:24Z

struct nand_ecclayout is too small for many new chips; OOB regions can be as large as 448 bytes and may increase more in the future. Thus, copying that struct to user-space with the ECCGETLAYOUT ioctl is not a good idea; the ioctl would have to be updated every time there's a change to the current largest size. Instead, the old nand_ecclayout is renamed to nand_ecclayout_user and a new struct nand_ecclayout is created that can accomodate larger sizes and expand without affecting the user-space. struct nand_ecclayout can still be used in board drivers without modification -- at least for now. A new function is provided to convert from the new to the old in order to allow the deprecated ioctl to continue to work with truncated data. Perhaps the ioctl, the conversion process, and the struct nand_ecclayout_user can be removed altogether in the future. Note: There are comments in nand/davinci_nand.c::nand_davinci_probe() regarding this issue; this driver (and maybe others) can be updated to account for extra space. All kernel drivers can use the expanded nand_ecclayout as a drop-in replacement and ignore its benefits. Signed-off-by: Brian Norris Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: add an ioctl to query the lock status of a flash sector

2010-08-02T08:03:41Z

This patchs adds a way for user space programs to find out whether a flash sector is locked. An optional driver method in the mtd_info struct provides the information. Signed-off-by: Richard Cochran Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

Kill jffs2-user.h

2009-06-05T16:31:38Z

This file does not define any kernel-userspace API, all it does it defines few helpers for userspace. Instead, userspace should have a private copy of this file. The main (if not the only) user is the mtd-utils package, but it already has a private copy of this file. This patch also removes references to 'jffs2-user.h' from 'Kbuild' and MAINTAINERS' files.
