  • fa0334f19   Replace pid_t in autofs with struct pid reference ... Browse Code »

    Make autofs container-friendly by caching struct pid reference rather than
    pid_t and using pid_nr() to retreive a task's pid_t.

    ChangeLog:
    - Fix Eric Biederman's comments - Use find_get_pid() to hold a
    reference to oz_pgrp and release while unmounting; separate out
    changes to autofs and autofs4.
    - Fix Cedric's comments: retain old prototype of parse_options()
    and move necessary change to its caller.

  • 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.

  • d8c76e6f4   [PATCH] r/o bind mount prepwork: inc_nlink() helper ... Browse Code »

    This is mostly included for parity with dec_nlink(), where we will have some
    more hooks. This one should stay pretty darn straightforward for now.

  • 9a53c3a78   [PATCH] r/o bind mounts: unlink: monitor i_nlink ... Browse Code »

    When a filesystem decrements i_nlink to zero, it means that a write must be
    performed in order to drop the inode from the filesystem.

    We're shortly going to have keep filesystems from being remounted r/o between
    the time that this i_nlink decrement and that write occurs.

    So, add a little helper function to do the decrements. We'll tie into it in a
    bit to note when i_nlink hits zero.

  • 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!
