2017-05-11uapi: export all headers under uapi directoriesNicolas Dichtel1-6/+0
Regularly, when a new header is created in include/uapi/, the developer forgets to add it in the corresponding Kbuild file. This error is usually detected after the release is out. In fact, all headers under uapi directories should be exported, thus it's useless to have an exhaustive list. After this patch, the following files, which were not exported, are now exported (with make headers_install_all): asm-arc/kvm_para.h asm-arc/ucontext.h asm-blackfin/shmparam.h asm-blackfin/ucontext.h asm-c6x/shmparam.h asm-c6x/ucontext.h asm-cris/kvm_para.h asm-h8300/shmparam.h asm-h8300/ucontext.h asm-hexagon/shmparam.h asm-m32r/kvm_para.h asm-m68k/kvm_para.h asm-m68k/shmparam.h asm-metag/kvm_para.h asm-metag/shmparam.h asm-metag/ucontext.h asm-mips/hwcap.h asm-mips/reg.h asm-mips/ucontext.h asm-nios2/kvm_para.h asm-nios2/ucontext.h asm-openrisc/shmparam.h asm-parisc/kvm_para.h asm-powerpc/perf_regs.h asm-sh/kvm_para.h asm-sh/ucontext.h asm-tile/shmparam.h asm-unicore32/shmparam.h asm-unicore32/ucontext.h asm-x86/hwcap2.h asm-xtensa/kvm_para.h drm/armada_drm.h drm/etnaviv_drm.h drm/vgem_drm.h linux/aspeed-lpc-ctrl.h linux/auto_dev-ioctl.h linux/bcache.h linux/btrfs_tree.h linux/can/vxcan.h linux/cifs/cifs_mount.h linux/coresight-stm.h linux/cryptouser.h linux/fsmap.h linux/genwqe/genwqe_card.h linux/hash_info.h linux/kcm.h linux/kcov.h linux/kfd_ioctl.h linux/lightnvm.h linux/module.h linux/nbd-netlink.h linux/nilfs2_api.h linux/nilfs2_ondisk.h linux/nsfs.h linux/pr.h linux/qrtr.h linux/rpmsg.h linux/sched/types.h linux/sed-opal.h linux/smc.h linux/smc_diag.h linux/stm.h linux/switchtec_ioctl.h linux/vfio_ccw.h linux/wil6210_uapi.h rdma/bnxt_re-abi.h Note that I have removed from this list the files which are generated in every exported directories (like .install or .install.cmd). Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all subdirs with a pure makefile command. For the record, note that exported files for asm directories are a mix of files listed by: - include/uapi/asm-generic/Kbuild.asm; - arch/<arch>/include/uapi/asm/Kbuild; - arch/<arch>/include/asm/Kbuild.

2014-03-06UBI: make UBI_IOCVOLCRBLK take a parameter for future usageEzequiel Garcia1-4/+15
In order to allow a future ioctl parameter, such as a creation flag, we change the UBI_IOCVOLCRBLK so it accepts a struct ubi_blkcreate_req. For the time being the structure is not in use, but fully reserved. This ABI change is still possible and harmless, because the ioctl has just been introduced and there's no userspace program which uses it.

2014-03-05UBI: rename block device ioctlsArtem Bityutskiy1-7/+7
Rename the UBI_IOCVOLATTBLK and UBI_IOCVOLDETBLK to UBI_IOCVOLCRBLK and UBI_IOCVOLRMBLK, because we do not use terms "attach" and "detach" for the R/O block devices on top of UBI volumes. Instead, we use terms "create" and "remove". This patch also amends the related commentaries.

2014-02-28UBI: R/O block driver on top of UBI volumesEzequiel Garcia1-0/+11
This commit introduces read-only block device emulation on top of UBI volumes. Given UBI takes care of wear leveling and bad block management it's possible to add a thin layer to enable block device access to UBI volumes. This allows to use a block-oriented filesystem on a flash device. The UBI block devices are meant to be used in conjunction with any regular, block-oriented file system (e.g. ext4), although it's primarily targeted at read-only file systems, such as squashfs. Block devices are created upon user request through new ioctls: UBI_IOCVOLATTBLK to attach and UBI_IOCVOLDETBLK to detach. Also, a new UBI module parameter is added 'ubi.block'. This parameter is needed in order to attach a block device on boot-up time, allowing to mount the rootfs on a ubiblock device. For instance, you could have these kernel parameters: ubi.mtd=5 ubi.block=0,0 root=/dev/ubiblock0_0 Or, if you compile ubi as a module: $ modprobe ubi mtd=/dev/mtd5 block=/dev/ubi0_0 Artem: amend commentaries and massage the patch a little bit.

2013-10-27mtd: nand: add more comment for MTD_NANDFLASH/MTD_MLCNANDFLASHHuang Shijie1-2/+2
In current code, the MTD_NANDFLASH is used to represent both the SLC and MLC. It is confusing to us. By adding an explicit comment about these two macros, this patch makes it clear that: MTD_NANDFLASH : stands for SLC NAND, MTD_MLCNANDFLASH : stands for MLC NAND (including TLC).

2013-05-29UBI: document UBI_IOCVOLUP better in user headerMike Frysinger1-1/+4
The current ioctl define implies that this func expects to be passed a 64bit number directly rather than a pointer to a 64bit. The code that processes this ioctl shows that it clearly expects a pointer. It'd be best if we could change the type to "__s64*", but that would change the generated ioctl number thus breaking the userland ABI. So just add a comment for intrepid developers.
