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.

Properly call btrfs_search_slot while shrinking · 1372f8e6

由 Chris Mason 提交于 1月 04, 2008

The shrinking code used btrfs_next_leaf to find the next item, but
this does not cow the blocks it touches. This fix calls search_slot after
finding the next item to do appropriate cow and balancing.

Btrfs: Properly handle overlapping extent in shrink_extent_tree · 73e48b27

由 Yan 提交于 1月 03, 2008

The patch fixes the overlapping extent issue in shrink_extent_tree.
It checks whether there is an overlapping extent by using
find_previous_extent. If there is an overlapping extent, it setups
key.objectid and cur_byte properly.

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.

Off by one fix for btrfs_drop_extents · 6e3b9666

由 Yan 提交于 12月 14, 2007

One of my old patches introduces a new bug to
btrfs_drop_extents(changeset 275). Inline extents are not truncated
properly when "extent_end == end", it can trigger the BUG_ON at
file.c:600.  I hope I don't introduce new bug this time.

Btrfs: section mismatch warnings · 17636e03

Hello everybody,

compiling btrfs into the kernel results in section mismatch warnings. __exit
functions are called where they are not allowed to. The attached patch fixes
this for me. Not sure if it is correct though.
