it looks slightly better performacewise with cold cache when compared
with Andries' patch:
Linus: 0.380u 76.850s 1:19.12 97.6% 0+0k 0+0io 113pf+0w
Andries: 0.470u 97.220s 1:40.29 97.4% 0+0k 0+0io 112pf+0w
BUT: there are some obvious bugs in the output of "du" and "find".
some samples (all file names (should) match the format "xe%03d/xe%03d.%c%c"
with both %03d being the _same_ number and both %c are in [a-z0-9]).
from "find" output:
...
/mnt/xe001/xe001.hg
find: /mnt/xe001/xe001.h: No such file or directory
/mnt/xe001/xe001.hi
...
/mnt/xe001/xe001.ib
find: /mnt/xe001/xe001.h: No such file or directory
/mnt/xe001/xe001.id

...
find: /mnt/xe004/xe003.rg: No such file or directory
...
find: /mnt/xe005/xe004.rg: No such file or directory
"find" from hot cache even shows some binary garbage:
...
/mnt/xe001/xe001.0k
find: /mnt/xe001/¶^¶ ¶¶p¶$¶^¶¶^¶^¶ ¶¶¶{}: No such file or directory
/mnt/xe001/xe001.0m

/mnt/xe001/xe001.gl

/mnt/xe105/xe105.p2
/mnt/xe105/x: No such file or directory
/mnt/xe001/xe001.gn
...
and from "du":
