  • 11ab83190   JFS: do not ignore return code from write_one_page() ... Browse Code »

    There are a couple places where jfs calls write_one_page() where clean
    recovery is not possible. In these cases, the file system should be
    marked dirty. To do this, it is now necessary to store the superblock in
    the metapage structure.

  • 09cbfeaf1   mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros ... Browse Code »

    PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
    ago with promise that one day it will be possible to implement page
    cache with bigger chunks than PAGE_SIZE.

    This promise never materialized. And unlikely will.

    We have many places where PAGE_CACHE_SIZE assumed to be equal to
    PAGE_SIZE. And it's constant source of confusion on whether
    PAGE_CACHE_* or PAGE_* constant should be used in a particular case,
    especially on the border between fs and mm.

    Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
    breakage to be doable.

    Let's stop pretending that pages in page cache are special. They are
    not.

    The changes are pretty straight-forward:

    - << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> ;

    - >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> ;

    - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};

    - page_cache_get() -> get_page();

    - page_cache_release() -> put_page();

    This patch contains automated changes generated with coccinelle using
    script below. For some reason, coccinelle doesn't patch header files.
    I've called spatch for them manually.

    The only adjustment after coccinelle is revert of changes to
    PAGE_CAHCE_ALIGN definition: we are going to drop it later.

    There are few places in the code where coccinelle didn't reach. I'll
    fix them manually in a separate patch. Comments and documentation also
    will be addressed with the separate patch.

  • ee1462458   fs, jfs: remove slab object constructor ... Browse Code »

    Mempools based on slab caches with object constructors are risky because
    element allocation can happen either from the slab cache itself, meaning
    the constructor is properly called before returning, or from the mempool
    reserve pool, meaning the constructor is not called before returning,
    depending on the allocation context.

    For this reason, we should disallow creating mempools based on slab caches
    that have object constructors. Callers of mempool_alloc() will be
    responsible for properly initializing the returned element.

    Then, it doesn't matter if the element came from the slab cache or the
    mempool reserved pool.

    The only occurrence of a mempool being based on a slab cache with an
    object constructor in the tree is in fs/jfs/jfs_metapage.c. Remove it and
    properly initialize the element in alloc_metapage().

    At the same time, META_free is never used, so remove it as well.

    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!
