Btrfs: Fix for test_range_bit · f0c5da14

Yan authored Jan 22, 2008

test_range_bit doesn't properly handle the case: there's a hole at the
end of the range and there's no other extent_state after the range.

Fix for btrfs_find_free_objectid · b1785427

Yan authored Jan 22, 2008

btrfs_find_free_objectid may return a used objectid due to arithmetic
underflow. This bug may happen when parameter 'root' is tree root, so
it may cause serious problems when creating snapshot or sub-volume.

Btrfs: Fix data=ordered vs wait_on_inode deadlock on older kernels · 4d5e74bc

Chris Mason authored Jan 16, 2008

Using ilookup5 during data=ordered writeback could deadlock on I_LOCK.  This

Btrfs: online shrinking fixes · c31f8830

Chris Mason authored Jan 08, 2008

While shrinking the FS, the allocation functions need to make sure
they don't try to allocate bytes past the end of the FS.

nodatacow needed an extra check to force cows when the existing extents are
past the end of the FS.

Btrfs: Move snapshot creation to commit time · 3063d29f

Chris Mason authored Jan 08, 2008

It is very difficult to create a consistent snapshot of the btree when
other writers may update the btree before the commit is done.

This changes the snapshot creation to happen during the commit, while
no other updates are possible.

Properly call btrfs_search_slot while shrinking · 1372f8e6

Chris Mason authored Jan 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

Yan authored Jan 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.
