• 9517bac6c   ocfs2: teach ocfs2_file_aio_write() about sparse files ... Browse Code »

  Unfortunately, ocfs2 can no longer make use of generic_file_aio_write_nlock()
  because allocating writes will require zeroing of pages adjacent to the I/O
  for cluster sizes greater than page size.

  Implement a custom file write here, which can order page locks for zeroing.
  This also has the advantage that cluster locks can easily be ordered outside
  of the page locks.

• dcd0538ff   ocfs2: sparse b-tree support ... Browse Code »

  Introduce tree rotations into the b-tree code. This will allow ocfs2 to
  support sparse files. Much of the added code is designed to be generic (in
  the ocfs2 sense) so that it can later be re-used to implement large
  extended attributes.

  This patch only adds the rotation code and does minimal updates to callers
  of the extent api.

• 92e1d5be9   [PATCH] mark struct inode_operations const 2 ... Browse Code »

  Many struct inode_operations in the kernel can be "const". Marking them const
  moves these to the .rodata section, which avoids false sharing with potential
  dirty data. In addition it'll catch accidental writes at compile time to
  these shared resources.

• d38eb8db6   ocfs2: implement i_op->permission ... Browse Code »

  Implement .permission() in ocfs2_file_iops, ocfs2_special_file_iops and
  ocfs2_dir_iops.

  This helps us avoid some multi-node races with mode change and vfs
  operations.

• 1fabe1481   ocfs2: Remove struct ocfs2_journal_handle in favor of handle_t ... Browse Code »

  This is mostly a search and replace as ocfs2_journal_handle is now no more
  than a container for a handle_t pointer.

  ocfs2_commit_trans() becomes very straight forward, and we remove some out
  of date comments / code.

• 4b6f5d20b   [PATCH] Make most file operations structs in fs/ const ... Browse Code »

  This is a conversion to make the various file_operations structs in fs/
  const. Basically a regexp job, with a few manual fixups

  The goal is both to increase correctness (harder to accidentally write to
  shared datastructures) and reducing the false sharing of cachelines with
  things that get dirty in .data (while .rodata is nicely read only and thus
  cache clean)
