      [PATCH] fix possible PAGE_CACHE_SHIFT overflows · 54b21a79
      Andrew Morton authored
      We've had two instances recently of overflows when doing
      
      	64_bit_value = (32_bit_value << PAGE_CACHE_SHIFT)
      
      I did a tree-wide grep of `<<.*PAGE_CACHE_SHIFT' and this is the result.
      
      - afs_rxfs_fetch_descriptor.offset is of type off_t, which seems broken.
      
      - jfs and jffs are limited to 4GB anyway.
      
      - reiserfs map_block_for_writepage() takes an unsigned long for the block -
        it should take sector_t.  (It'll fail for huge filesystems with
        blocksize<PAGE_CACHE_SIZE)
      
      - cramfs_read() needs to use sector_t (I think cramsfs is busted on large
        filesystems anyway)
      
      - affs is limited in file size anyway.
      
      - I generally didn't fix 32-bit overflows in directory operations.
      
      - arm's __flush_dcache_page() is peculiar.  What if the page lies beyond 4G?
      
      - gss_wrap_req_priv() needs checking (snd_buf->page_base)

      [PATCH] add AOP_TRUNCATED_PAGE, prepend AOP_ to WRITEPAGE_ACTIVATE · 994fc28c
      Zach Brown authored
      readpage(), prepare_write(), and commit_write() callers are updated to
      understand the special return code AOP_TRUNCATED_PAGE in the style of
      writepage() and WRITEPAGE_ACTIVATE.  AOP_TRUNCATED_PAGE tells the caller that
      the callee has unlocked the page and that the operation should be tried again
      with a new page.  OCFS2 uses this to detect and work around a lock inversion in
      its aop methods.  There should be no change in behaviour for methods that don't
      return AOP_TRUNCATED_PAGE.
      
      WRITEPAGE_ACTIVATE is also prepended with AOP_ for consistency and they are
      made enums so that kerneldoc can be used to document their semantics.

      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!
