mainlining shenanigans

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: Chris Mason <chris.mason@oracle.com> |
