Btrfs: Properly clear dirty and delalloc extent bits while preparing the file for write · 0762704b

Chris Mason authored Feb 19, 2008

Yan Zheng noticed that we don't clear the extent state tree dirty and delalloc
bits when we clear the dirty bits on the page during file write.

This leads to csum errors later on.

Btrfs: Allocator improvements · d7fc640e

Chris Mason authored Feb 18, 2008

Reduce CPU time searching for free blocks by optimizing find_first_extent_bit

Fix find_free_extent to make better use of the last_alloc hint. Before it
was often finding blocks just before the hint.

Btrfs: unaligned access fixes · df68b8a7

David Miller authored Feb 15, 2008

Btrfs set/get macros lose type information needed to avoid
unaligned accesses on sparc64.
ere is a patch for the kernel bits which fixes most of the
unaligned accesses on sparc64.

btrfs_name_hash is modified to return the hash value instead
of getting a return location via a (potentially unaligned)
pointer.

Btrfs: Fix i_blocks accounting · 9069218d

Chris Mason authored Feb 08, 2008

Now that delayed allocation accounting works, i_blocks accounting is changed
to only modify i_blocks when extents inserted or removed.

The fillattr call is changed to include the delayed allocation byte count
in the i_blocks result.

Call btrfs_cow_block while lowering tree level. · 2f375ab9

Yan authored Feb 01, 2008

When freeing root block of a tree,  btrfs_free_extent' parameter
'ref_generation' is from root block itseft.  When freeing non-root
block,  'ref_generation' is from its parent. so when converting a
non-root block to root block, we must guarantee its generation is
equal to its parent's generation.

Btrfs: extent_io and extent_state optimizations · 70dec807

Chris Mason authored Jan 29, 2008

The end_bio routines are changed to take a pointer to the extent state
struct, and the state tree is walked in order to set/clear appropriate
bits as IO completes.  This greatly reduces the number of rbtree searches
done by the end_bio handlers, and reduces lock contention.

The extent_io releasepage function is changed to avoid expensive searches
for locked state.
