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. Signed-off-by: NChris Mason <chris.mason@oracle.com>

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. Signed-off-by: NChris Mason <chris.mason@oracle.com>

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. --- Signed-off-by: NChris Mason <chris.mason@oracle.com>

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. Signed-off-by: NChris Mason <chris.mason@oracle.com>

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%. Signed-off-by: NChris Mason <chris.mason@oracle.com>

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. Signed-off-by: NChris Mason <chris.mason@oracle.com>
