It seems that the rate of spurious I/O errors varies most according to
the vm.vfs_cache_pressure sysctl. At '10' the I/O errors occur so often
that building a kernel is impossible. At '100' I can't reproduce even
a single I/O error.
I guess this is own my fault for using non-default sysctl

Before this patch, csum tree rebuild will not work with extent tree
rebuild, since extent tree rebuild will only build up basic block
groups, but csum tree rebuild needs data extents to rebuild.
So if one use btrfsck with --init-csum-tree and --init-extent-tree, csum
tree will be empty and tons of

My miss, I don't notice feature and label change by sysfs.
