Btrfs: Handle data block end_io through the async work queue · 22c59948

由 Chris Mason 提交于 4月 09, 2008

Before it was done by the bio end_io routine, the work queue code is able
to scale much better with faster IO subsystems.

Btrfs: Verify checksums on tree blocks found without read_tree_block · 0999df54

由 Chris Mason 提交于 4月 01, 2008

Checksums were only verified by btrfs_read_tree_block, which meant the
functions to probe the page cache for blocks were not validating checksums.
Normally this is fine because the buffers will only be in cache if they
have already been validated.

But, there is a window while the buffer is being read from disk where
it could be up to date in the cache but not yet verified.  This patch
makes sure all buffers go through checksum verification before they
are used.

This is safer, and it prevents modification of buffers before they go
through the csum code.

Btrfs: Add data=ordered support · dc17ff8f

由 Chris Mason 提交于 1月 08, 2008

This forces file data extents down the disk along with the metadata that
references them. The current implementation is fairly simple, and just
writes out all of the dirty pages in an inode before the commit.

Btrfs: Use balance_dirty_pages_nr on btree blocks · d3c2fdcf

由 Chris Mason 提交于 9月 17, 2007

btrfs_btree_balance_dirty is changed to pass the number of pages dirtied
for more accurate dirty throttling.  This lets the VM make better decisions
about when to force some writeback.

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.
