  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 full_scan parameter to find_search_start · 5e5745dc
  由 Yan 提交于 11月 16, 2007
```
This patch adds a new parameter 'full_scan' to 'find_search_start',
thereby 'find_search_start' can know whether 'find_free_extent' is in
full scan phrase. I feel that 'find_search_start' should skip calling
'btrfs_find_block_group' when 'find_free_extent' is in full scan
phrase. In my test on a 2GB volume, Oops occurs when space usage is
about 76%. After apply the patch,  Oops occurs when space usage is
near 100%.

'update_block_group',  the last parameter of the function indicates
pin vs unpin.
