  • 621e155a3   fs: change d_compare for rcu-walk ... Browse Code »

    Change d_compare so it may be called from lock-free RCU lookups. This
    does put significant restrictions on what may be done from the callback,
    however there don't seem to have been any problems with in-tree fses.
    If some strange use case pops up that _really_ cannot cope with the
    rcu-walk rules, we can just add new rcu-unaware callbacks, which would
    cause name lookup to drop out of rcu-walk mode.

    For in-tree filesystems, this is just a mechanical change.

  • 2e54eb96e   BKL: Remove BKL from ncpfs ... Browse Code »

    Dozen of changes in ncpfs to provide some locking other than BKL.

    In readdir cache unlock and mark complete first page as last operation,
    so it can be used for synchronization, as code intended.

    When updating dentry name on case insensitive filesystems do at least
    some basic locking...

    Hold i_mutex when updating inode fields.

    Push some ncp_conn_is_valid down to ncp_request. Connection can become
    invalid at any moment, and fewer error code paths to test the better.

    Use i_size_{read,write} to modify file size.

    Set inode's backing_dev_info as ncpfs has its own special bdi.

    In ioctl unbreak ioctls invoked on filesystem mounted 'ro' - tests are
    for inode writeable or owner match, but were turned to filesystem
    writeable and inode writeable or owner match. Also collect all permission
    checks in single place.

    Add some locking, and remove comments saying that it would be cool to
    add some locks to the code.

    Constify some pointers.

  • d52988023   Remove the last few UMSDOS leftovers ... Browse Code »

    The UMSDOS filesystem was removed back in 2.6.11, but some tiny bits stuck
    around. This patch removes the few remaining leftovers. The only things
    left behind after this are the entries in the CREDITS file and the ioctl
    number in Documentation/ioctl-number.txt as documentation.

    This third (hopefully final) version of the patch doesn't edit the
    arch/um/config.release file, since Jeff Dike pointed out to me that it
    should die completely, and asked me to remove it from my patch as he'll
    send in a seperate patch removing the file completely.

  • c5ef1c42c   [PATCH] mark struct inode_operations const 3 ... 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.

  • 54f67f631   [PATCH] Move ncpfs 32bit compat ioctl to ncpfs ... Browse Code »

    The ncp specific compat ioctls are clearly local to one file system, so the
    code can better live there.

    This version of the patch moves everything into the generic ioctl handler
    and uses it for both 32 and 64 bit calls.

  • 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)

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    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!
