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

  • There are two places that do so - the cgroups subsystem and the autofs
    code.

  • The set of functions process_session, task_session, process_group and
    task_pgrp is confusing, as the names can be mixed with each other when looking
    at the code for a long time.

    The proposals are to
    * equip the functions that return the integer with _nr suffix to
    represent that fact,
    * and to make all functions work with task (not process) by making
    the common prefix of the same name.

    For monotony the routines signal_session() and set_signal_session() are
    replaced with task_session_nr() and set_task_session(), especially since they
    are only used with the explicit task->signal dereference.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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!
