      Documentation: get rid of write_super · 34e5053f
      Artem Bityutskiy authored
      
      
      The '->write_super' superblock method is gone, and this patch removes all the
      references to 'write_super' from various pieces of the kernel documentation.

      vfs: kill write_super and sync_supers · f0cd2dbb
      Artem Bityutskiy authored
      
      
      Finally we can kill the 'sync_supers' kernel thread along with the
      '->write_super()' superblock operation because all the users are gone.
      Now every file-system is supposed to self-manage own superblock and
      its dirty state.
      
      The nice thing about killing this thread is that it improves power management.
      Indeed, 'sync_supers' is a source of monotonic system wake-ups - it woke up
      every 5 seconds no matter what - even if there were no dirty superblocks and
      even if there were no file-systems using this service (e.g., btrfs and
      journalled ext4 do not need it). So it was wasting power most of the time. And
      because the thread was in the core of the kernel, all systems had to have it.
      So I am quite happy to make it go away.
      
      Interestingly, this thread is a left-over from the pdflush kernel thread which
      was a self-forking kernel thread responsible for all the write-back in old
      Linux kernels. It was turned into per-block device BDI threads, and
      'sync_supers' was a left-over. Thus, R.I.P, pdflush as well.

       - Fixes a bug when the lower filesystem mount options include 'acl',

       - Cleanups in the messaging code
       - Better handling of empty files in the lower filesystem to improve
         usability.  Failed file creations are now cleaned up and empty lower
         files are converted into eCryptfs during open().
       - The write-through cache changes are being reverted due to bugs that
         are not easy to fix.  Stability outweighs the performance
         enhancements here.
       - Improvement to the mount code to catch unsupported ciphers specified

      ceph: simplify+fix atomic_open · 5ef50c3b
      Sage Weil authored
      
      
      The initial ->atomic_open op was carried over from the old intent code,
      which was incomplete and didn't really work.  Replace it with a fresh
      method.  In particular:
      
       * always attempt to do an atomic open+lookup, both for the create case
         and for lookups of existing files.
       * fix symlink handling by returning 1 to the VFS so that we can follow
         the link to its destination. This fixes a longstanding ceph bug (#2392).

      ore: Fix out-of-bounds access in _ios_obj() · 9e62bb44
      Boaz Harrosh authored
      
      
      _ios_obj() is accessed by group_index not device_table index.
      
      The oc->comps array is only a group_full of devices at a time
      it is not like ore_comp_dev() which is indexed by a global
      device_table index.
      
      This did not BUG until now because exofs only uses a single
      COMP for all devices. But with other FSs like PanFS this is
      not true.
      
      This bug was only in the write_path, all other users were
      using it correctly

      exofs: Fix __r4w_get_page when offset is beyond i_size · 4b74f6ea
      Boaz Harrosh authored
      
      
      It is very common for the end of the file to be unaligned on
      stripe size. But since we know it's beyond file's end then
      the XOR should be preformed with all zeros.
      
      Old code used to just read zeros out of the OSD devices, which is a great
      waist. But what scares me more about this situation is that, we now have
      pages attached to the file's mapping that are beyond i_size. I don't
      like the kind of bugs this calls for.
      
      Fix both birds, by returning a global ZERO_PAGE, if offset is beyond
      i_size.

      exofs: stop using s_dirt · 66153f6e
      Artem Bityutskiy authored
      
      
      Exofs has the '->write_super()' handler and makes some use of the '->s_dirt'
      superblock flag, but it really needs neither of them because it never sets
      's_dirt' to one which means the VFS never calls its '->write_super()' handler.
      Thus, remove both.
      
      Note, I am trying to remove both 's_dirt' and 'write_super()' from VFS
      altogether once all users are gone.

      readpage_strip can be called from several code paths all of which

      Since we export the exofs_readpage callback to the VFS, add a

      Check if the chip has provided a write operation (which is mandatory for

      for this. Also skip the attempt if there's no regmap available by device
      in case things get confused by the attempt to default.
