  • e62438630   [PATCH] Centralise definitions of sector_t and blkcnt_t ... Browse Code »

    CONFIG_LBD and CONFIG_LSF are spread into asm/types.h for no particularly
    good reason.

    Centralising the definition in linux/types.h means that arch maintainers
    don't need to bother adding it, as well as fixing the problem with
    x86-64 users being asked to make a decision that has absolutely no
    effect.

    The H8/300 porters seem particularly confused since I'm not aware of any
    microcontrollers that need to support 2TB filesystems.

    It's too easy for people to shoot themselves in the foot, and it
    only makes sense for embedded folks anyway.

  • 9361401eb   [PATCH] BLOCK: Make it possible to disable the block layer [try #6] ... Browse Code »

    Make it possible to disable the block layer. Not all embedded devices require
    it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require
    the block layer to be present.

    This patch does the following:

    (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev
    support.

    (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls
    an item that uses the block layer. This includes:

    (*) Block I/O tracing.

    (*) Disk partition code.

    (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS.

    (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the
    block layer to do scheduling. Some drivers that use SCSI facilities -
    such as USB storage - end up disabled indirectly from this.

    (*) Various block-based device drivers, such as IDE and the old CDROM
    drivers.

    (*) MTD blockdev handling and FTL.

    (*) JFFS - which uses set_bdev_super(), something it could avoid doing by
    taking a leaf out of JFFS2's book.

    (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and
    linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is,
    however, still used in places, and so is still available.

    (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and
    parts of linux/fs.h.

    (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.

    (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.

    (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK
    is not enabled.

    (*) fs/no-block.c is created to hold out-of-line stubs and things that are
    required when CONFIG_BLOCK is not set:

    (*) Default blockdev file operations (to give error ENODEV on opening).

    (*) Makes some /proc changes:

    (*) /proc/devices does not list any blockdevs.

    (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.

    (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.

    (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if
    given command other than Q_SYNC or if a special device is specified.

    (*) In init/do_mounts.c, no reference is made to the blockdev routines if
    CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2.

    (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return
    error ENOSYS by way of cond_syscall if so).

    (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if
    CONFIG_BLOCK is not set, since they can't then happen.

  • 88b9adb07   [PATCH] config: fix CONFIG_LFS option ... Browse Code »

    The help text says that if you select CONFIG_LBD, then it will automatically
    select CONFIG_LFS. That isn't currently the case, so update the text.

    - Get rid of the cruft in the help text mentioning CONFIG_LBD

    - Tell unsure users to select CONFIG_LFS.

    - Remove the `default n'.

  • a0f62ac63   [PATCH] 2TB files: add blkcnt_t ... Browse Code »

    Add blkcnt_t as the type of inode.i_blocks. This enables you to make the size
    of blkcnt_t either 4 bytes or 8 bytes on 32 bits architecture with CONFIG_LSF.

    - CONFIG_LSF
    Add new configuration parameter.
    - blkcnt_t
    On h8300, i386, mips, powerpc, s390 and sh that define sector_t,
    blkcnt_t is defined as u64 if CONFIG_LSF is enabled; otherwise it is
    defined as unsigned long.
    On other architectures, it is defined as unsigned long.
    - inode.i_blocks
    Change the type from sector_t to blkcnt_t.
