  • 1b061d924   rename the generic fsync implementations ... Browse Code »

    We don't name our generic fsync implementations very well currently.
    The no-op implementation for in-memory filesystems currently is called
    simple_sync_file which doesn't make too much sense to start with,
    the the generic one for simple filesystems is called simple_fsync
    which can lead to some confusion.

    This patch renames the generic file fsync method to generic_file_fsync
    to match the other generic_file_* routines it is supposed to be used
    with, and the no-op implementation to noop_fsync to make it obvious
    what to expect. In addition add some documentation for both methods.

  • 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.

  • 543ade1fc   [PATCH] Streamline generic_file_* interfaces and filemap cleanups ... Browse Code »

    This patch cleans up generic_file_*_read/write() interfaces. Christoph
    Hellwig gave me the idea for this clean ups.

    In a nutshell, all filesystems should set .aio_read/.aio_write methods and use
    do_sync_read/ do_sync_write() as their .read/.write methods. This allows us
    to cleanup all variants of generic_file_* routines.

    Final available interfaces:

    generic_file_aio_read() - read handler
    generic_file_aio_write() - write handler
    generic_file_aio_write_nolock() - no lock write handler

    __generic_file_aio_write_nolock() - internal worker routine

  • 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!
