  Btrfs: Implement basic support for -ENOSPC · 1832a6d5
  由 Chris Mason 提交于 12月 21, 2007
```
This is intended to prevent accidentally filling the drive.  A determined
user can still make things oops.

It includes some accounting of the current bytes under delayed allocation,
but this will change as things get optimized

  Btrfs: Add mount option to turn off data cow · be20aa9d
  由 Chris Mason 提交于 12月 17, 2007
```
A number of workloads do not require copy on write data or checksumming.
mount -o nodatasum to disable checksums and -o nodatacow to disable
both copy on write and checksumming.

In nodatacow mode, copy on write is still performed when a given extent
is under snapshot.

  Btrfs: Add block group pinned accounting back · 324ae4df
  由 Yan 提交于 11月 16, 2007
```
This patch adds a helper function 'update_pinned_extents' to
extent-tree.c. The usage of the helper function is similar to
'update_block_group',  the last parameter of the function indicates
pin vs unpin.

  Btrfs: Fix a number of inline extent problems that Yan Zheng reported. · 179e29e4
  由 Chris Mason 提交于 11月 01, 2007
```
The fixes do a number of things:

1) Most btrfs_drop_extent callers will try to leave the inline extents in
place.  It can truncate bytes off the beginning of the inline extent if
required.

2) writepage can now update the inline extent, allowing mmap writes to
go directly into the inline extent.

3) btrfs_truncate_in_transaction truncates inline extents

4) extent_map.c fixed to not merge inline extent mappings and hole
mappings together

Btrfs: Find and remove dead roots the first time a root is loaded. · 5ce14bbc

由 Chris Mason 提交于 9月 11, 2007

Dead roots are trees left over after a crash, and they were either in the
process of being removed or were waiting to be removed when the box crashed.
Before, a search of the entire tree of root pointers was done on mount
looking for dead roots. Now, the search is done the first time we load
a root.

This makes mount faster when there are a large number of snapshots, and it
enables the block accounting code to properly update the block counts on
the latest root as old versions of the root are reaped after a crash.

Btrfs: Add more synchronization before creating a snapshot · 011410bd

由 Chris Mason 提交于 9月 10, 2007

File data checksums are only done during writepage, so we have to make sure
all pages are written when the snapshot is taken. This also adds some
locking so that new writes don't race in and add new dirty pages.
