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

Thanks,
Eryu
