  • da23ef054   adfs: add hexadecimal filetype suffix option ... Browse Code »

    ADFS (FileCore) storage complies with the RISC OS filetype specification
    (12 bits of file type information is stored in the file load address,
    rather than using a file extension). The existing driver largely ignores
    this information and does not present it to the end user.

    It is desirable that stored filetypes be made visible to the end user to
    facilitate a precise copy of data and metadata from a hard disc (or image
    thereof) into a RISC OS emulator (such as RPCEmu) or to a network share
    which can be accessed by real Acorn systems.

    This patch implements a per-mount filetype suffix option (use -o
    ftsuffix=1) to present any filetype as a ,xyz hexadecimal suffix on each
    file. This type suffix is compatible with that used by RISC OS systems
    that access network servers using NFS client software and by RPCemu's host
    filing system.

  • 2f09719af   adfs: fix E+/F+ dir size > 2048 crashing kernel ... Browse Code »

    Kernel crashes in fs/adfs module when accessing directories with a large
    number of objects on mounted Acorn ADFS E+/F+ format discs (or images) as
    the existing code writes off the end of the fixed array of struct
    buffer_head pointers.

    Additionally, each directory access that didn't crash would leak a buffer
    as nr_buffers was not adjusted correctly for E+/F+ discs (was always left
    as one less than required).

    The patch fixes this by allocating a dynamically-sized set of struct
    buffer_head pointers if necessary for the E+/F+ case (many directories
    still do in fact fit in 2048 bytes) and sets the correct nr_buffers so
    that all buffers are released.

    Addresses https://bugzilla.kernel.org/show_bug.cgi?id=26072

    Tested by tar'ing the contents of my RISC PC's E+ format 20Gb HDD which
    contains a number of large directories that previously crashed the kernel.

    This gives the filesystem more information about the writeback that
    is happening. Trond requested this for the NFS unstable write handling,
    and other filesystems might benefit from this too by beeing able to
    distinguish between the different callers in more detail.

  • 754661f14   [PATCH] mark struct inode_operations const 1 ... Browse Code »

    Many struct inode_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • 4b6f5d20b   [PATCH] Make most file operations structs in fs/ const ... Browse Code »

    This is a conversion to make the various file_operations structs in fs/
    const. Basically a regexp job, with a few manual fixups

    The goal is both to increase correctness (harder to accidentally write to
    shared datastructures) and reducing the false sharing of cachelines with
    things that get dirty in .data (while .rodata is nicely read only and thus
    cache clean)

  • 733482e44   [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason ... Browse Code »

    This patch removes almost all inclusions of linux/version.h. The 3
    #defines are unused in most of the touched files.

    A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
    unfortunatly in linux/version.h.

    There are also lots of #ifdef for long obsolete kernels, this was not
    touched. In a few places, the linux/version.h include was move to where
    the LINUX_VERSION_CODE was used.

    quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`

    search pattern:
    /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
