I excluded the writeback tracepoints you mentioned writeback_mark_inode_dirty writeback_dirty_inode_start writeback_dirty_inode writeback_dirty_page writeback_write_inode and left all other writeback tracepoints enabled, also dropped xfs_file_buffered_write and xfs_file_fsync. This time I can reproduce generic/048 quickly and please download the trace info from below http://128.199.137.77/writeback-v2/ Thanks, Eryu |
