      mm: Remove slab destructors from kmem_cache_create(). · 20c2df83
      Paul Mundt authored
      Slab destructors were no longer supported after Christoph's
      c59def9f change. They've been
      BUGs for both slab and slub, and slob never supported them
      either.
      
      This rips out support for the dtor pointer from kmem_cache_create()
      completely and fixes up every single callsite in the kernel (there were
      about 224, not including the slab allocator definitions themselves,
      or the documentation references).

      SLAB_CTOR_CONSTRUCTOR is always specified. No point in checking it.

      slab allocators: Remove SLAB_DEBUG_INITIAL flag · 50953fe9
      Christoph Lameter authored
      I have never seen a use of SLAB_DEBUG_INITIAL.  It is only supported by
      SLAB.
      
      I think its purpose was to have a callback after an object has been freed
      to verify that the state is the constructor state again?  The callback is
      performed before each freeing of an object.
      
      I would think that it is much easier to check the object state manually
      before the free.  That also places the check near the code object
      manipulation of the object.
      
      Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was
      compiled with SLAB debugging on.  If there would be code in a constructor
      handling SLAB_DEBUG_INITIAL then it would have to be conditional on
      SLAB_DEBUG otherwise it would just be dead code.  But there is no such code
      in the kernel.  I think SLUB_DEBUG_INITIAL is too problematic to make real
      use of, difficult to understand and there are easier ways to accomplish the
      same effect (i.e.  add debug code before kfree).
      
      There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be
      clear in fs inode caches.  Remove the pointless checks (they would even be
      pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors.
      
      This is the last slab flag that SLUB did not support.  Remove the check for
      unimplemented flags from SLUB.

      [PATCH] VFS: Permit filesystem to override root dentry on mount · 454e2398
      David Howells authored
      Extend the get_sb() filesystem operation to take an extra argument that
      permits the VFS to pass in the target vfsmount that defines the mountpoint.
      
      The filesystem is then required to manually set the superblock and root dentry
      pointers.  For most filesystems, this should be done with simple_set_mnt()
      which will set the superblock pointer and then set the root dentry to the
      superblock's s_root (as per the old default behaviour).
      
      The get_sb() op now returns an integer as there's now no need to return the
      superblock pointer.
      
      This patch permits a superblock to be implicitly shared amongst several mount
      points, such as can be done with NFS to avoid potential inode aliasing.  In
      such a case, simple_set_mnt() would not be called, and instead the mnt_root
      and mnt_sb would be set directly.
      
      The patch also makes the following changes:
      
       (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount
           pointer argument and return an integer, so most filesystems have to change
           very little.
      
       (*) If one of the convenience function is not used, then get_sb() should
           normally call simple_set_mnt() to instantiate the vfsmount. This will
           always return 0, and so can be tail-called from get_sb().
      
       (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the
           dcache upon superblock destruction rather than shrink_dcache_anon().
      
           This is required because the superblock may now have multiple trees that
           aren't actually bound to s_root, but that still need to be cleaned up. The
           currently called functions assume that the whole tree is rooted at s_root,
           and that anonymous dentries are not the roots of trees which results in
           dentries being left unculled.
      
           However, with the way NFS superblock sharing are currently set to be
           implemented, these assumptions are violated: the root of the filesystem is
           simply a dummy dentry and inode (the real inode for '/' may well be
           inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries
           with child trees.
      
           [*] Anonymous until discovered from another tree.
      
       (*) The documentation has been adjusted, including the additional bit of
           changing ext2_* into foo_* in the documentation.

      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!
