  • f4e420dc4   clean up write_begin usage for directories in pagecache ... Browse Code »

    For filesystem that implement directories in pagecache we call
    block_write_begin with an already allocated page for this code, while the
    normal regular file write path uses the default block_write_begin behaviour.

    Get rid of the __foofs_write_begin helper and opencode the normal write_begin
    call in foofs_write_begin, while adding a new foofs_prepare_chunk helper for
    the directory code. The added benefit is that foofs_prepare_chunk has
    a much saner calling convention.

    Note that the interruptible flag passed into block_write_begin is always
    ignored if we already pass in a page (see next patch for details), and
    we never were doing truncations of exessive blocks for this case either so we
    can switch directly to block_write_begin_newtrunc.

  • a9185b41a   pass writeback_control to ->write_inode ... Browse Code »

    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.

  • b8e1343f6   iget: stop the SYSV filesystem from using iget() and read_inode() ... Browse Code »

    Stop the SYSV filesystem from using iget() and read_inode(). Replace
    sysv_read_inode() with sysv_iget(), and call that instead of iget().
    sysv_iget() then uses iget_locked() directly and returns a proper error code
    instead of an inode in the event of an error.

  • 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.

  • 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)

    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!
