• a4ffdde6e   simplify checks for I_CLEAR/I_FREEING ... Browse Code »

  add I_CLEAR instead of replacing I_FREEING with it. I_CLEAR is
  equivalent to I_FREEING for almost all code looking at either;
  it's there to keep track of having called clear_inode() exactly
  once per inode lifetime, at some point after having set I_FREEING.
  I_CLEAR and I_FREEING never get set at the same time with the
  current code, so we can switch to setting i_flags to I_FREEING | I_CLEAR
  instead of I_CLEAR without loss of information. As the result of
  such change, checks become simpler and the amount of code that needs
  to know about I_CLEAR shrinks a lot.

• c3ea56c80   nilfs2: flush palloc cache before manipulating data pages of GC dat ... Browse Code »

  Data pages in gcdat metadata file (i.e. the secondary DAT for GC), are
  cleared or even moved back to the normal DAT when a shot of garbage
  collection was done.

  Buffer heads held by the palloc cache of gcdat must be cleared before
  these page cache manipulation. This adds nilfs_palloc_clear_cache()
  to ensure this.

• 84ef1ecfd   nilfs2: another dat for garbage collection ... Browse Code »

  NILFS2 uses another DAT inode during garbage collection to ensure
  atomicity and consistency of the DAT in the transient state. This
  twin inode is called GCDAT.

  This adds functions to initialize the GCDAT and to switch page caches
  and B-tree node caches between these two inodes.
