Btrfs: Add BH_Defrag to mark buffers that are in need of defragging · f2183bde

由 Chris Mason 提交于 8月 10, 2007

This allows the tree walking code to defrag only the newly allocated
buffers, it seems to be a good balance between perfect defragging and the
performance hit of repeatedly reallocating blocks.

Btrfs: Add run time btree defrag, and an ioctl to force btree defrag · 6702ed49

由 Chris Mason 提交于 8月 07, 2007

This adds two types of btree defrag, a run time form that tries to
defrag recently allocated blocks in the btree when they are still in ram,
and an ioctl that forces defrag of all btree blocks.

File data blocks are not defragged yet, but this can make a huge difference
in sequential btree reads.
