      ext4: suppress ext4 orphan messages on mount · 566370a2
      Paul Taysom 提交于
      Suppress the messages releating to processing the ext4 orphan list
      ("truncating inode" and "deleting unreferenced inode") unless the
      debug option is on, since otherwise they end up taking up space in the
      log that could be used for more useful information.
      
      Tested by opening several files, unlinking them, then
      crashing the system, rebooting the system and examining
      /var/log/messages.

      jbd2: fix block tag checksum verification brokenness · eee06c56
      Darrick J. Wong 提交于
      Al Viro complained of a ton of bogosity with regards to the jbd2 block
      tag header checksum.  This one checksum is 16 bits, so cut off the
      upper 16 bits and treat it as a 16-bit value and don't mess around
      with be32* conversions.  Fortunately metadata checksumming is still
      "experimental" and not in a shipping e2fsprogs, so there should be few
      users affected by this.

      ext4: make punch hole code path work with bigalloc · d23142c6
      Lukas Czerner 提交于
      Currently punch hole is disabled in file systems with bigalloc
      feature enabled. However the recent changes in punch hole patch should
      make it easier to support punching holes on bigalloc enabled file
      systems.
      
      This commit changes partial_cluster handling in ext4_remove_blocks(),
      ext4_ext_rm_leaf() and ext4_ext_remove_space(). Currently
      partial_cluster is unsigned long long type and it makes sure that we
      will free the partial cluster if all extents has been released from that
      cluster. However it has been specifically designed only for truncate.
      
      With punch hole we can be freeing just some extents in the cluster
      leaving the rest untouched. So we have to make sure that we will notice
      cluster which still has some extents. To do this I've changed
      partial_cluster to be signed long long type. The only scenario where
      this could be a problem is when cluster_size == block size, however in
      that case there would not be any partial clusters so we're safe. For
      bigger clusters the signed type is enough. Now we use the negative value
      in partial_cluster to mark such cluster used, hence we know that we must
      not free it even if all other extents has been freed from such cluster.
      
      This scenario can be described in simple diagram:
      
      |FFF...FF..FF.UUU|
       ^----------^
        punch hole
      
      . - free space
      | - cluster boundary
      F - freed extent
      U - used extent
      
      Also update respective tracepoints to use signed long long type for
      partial_cluster.

      Lukas Czerner 提交于
      The "head removal" branch in the condition is never used in any code
      path in ext4 since the function only caller ext4_ext_rm_leaf() will make
      sure that the extent is properly split before removing blocks. Note that
      there is a bug in this branch anyway.

      ext4: use ext4_zero_partial_blocks in punch_hole · a87dd18c
      Lukas Czerner 提交于
      We're doing to get rid of ext4_discard_partial_page_buffers() since it is
      duplicating some code and also partially duplicating work of
      truncate_pagecache_range(), moreover the old implementation was much
      clearer.
      
      Now when the truncate_inode_pages_range() can handle truncating non page
      aligned regions we can use this to invalidate and zero out block aligned
      region of the punched out range and then use ext4_block_truncate_page()
      to zero the unaligned blocks on the start and end of the range. This
      will greatly simplify the punch hole code. Moreover after this commit we
      can get rid of the ext4_discard_partial_page_buffers() completely.
      
      We also introduce function ext4_prepare_punch_hole() to do come common
      operations before we attempt to do the actual punch hole on
      indirect or extent file which saves us some code duplication.
      
      This has been tested on ppc64 with 1k block size with fsx and xfstests
      without any problems.

      Revert "ext4: fix fsx truncate failure" · eb3544c6
      Lukas Czerner 提交于
      This reverts commit 189e868f.
      
      This commit reintroduces the use of ext4_block_truncate_page() in ext4
      truncate operation instead of ext4_discard_partial_page_buffers().
      
      The statement in the commit description that the truncate operation only
      zero block unaligned portion of the last page is not exactly right,
      since truncate_pagecache_range() also zeroes and invalidate the unaligned
      portion of the page. Then there is no need to zero and unmap it once more
      and ext4_block_truncate_page() was doing the right job, although we
      still need to update the buffer head containing the last block, which is
      exactly what ext4_block_truncate_page() is doing.
      
      Moreover the problem described in the commit is fixed more properly with
      commit

      mm: teach truncate_inode_pages_range() to handle non page aligned ranges · 5a720394
      Lukas Czerner 提交于
      This commit changes truncate_inode_pages_range() so it can handle non
      page aligned regions of the truncate. Currently we can hit BUG_ON when
      the end of the range is not page aligned, but we can handle unaligned
      start of the range.
      
      Being able to handle non page aligned regions of the page can help file
      system punch_hole implementations and save some work, because once we're
      holding the page we might as well deal with it right away.
      
      In previous commits we've changed ->invalidatepage() prototype to accept
      'length' argument to be able to specify range to invalidate. No we can
      use that new ability in truncate_inode_pages_range().

      Pull devm usage cleanup from Wolfram Sang:
       "Lately, I have been experimenting how to improve the devm interface to
        make writing device drivers easier and less error prone while also
        getting rid of its subtle issues.  I think it has more potential but
        still needs work and definately conistency, especiall in its usage.
      
        The first thing I come up with is a low hanging fruit regarding
        devm_ioremap_resouce().  This function already checks if the passed
        resource is valid and gives an error message if not.  So, we can
        remove similar checks from the drivers and get rid of a bit of code
        and a number of inconsistent error strings.
      
        This series only removes the unneeded check iff devm_ioremap_resource
        follows platform_get_resource directly.  The previous version tried to
        shuffle code if needed, too, what lead to an embarrasing bug.  It
        turned out to me that shuffling code for all cases found will make the
        automated script too complex, so I am unsure if an automated cleanup
        is the proper tool for this case.  Removing the easy stuff seems
        worthwhile to me, though.
      
        Despite various architectures and platform dependencies, I managed to
        compile test 45 out of 57 modified files locally using heuristics and
