On systems with block devices containing slashes (virtual dasd, cciss,

it being interpreted as a subdirectory. The generic block device code
changes the / to ! for use in the sysfs tree. This patch uses that
convention.



Isn't it a bit dumb of us to be putting slashes in the device names anyway?
It would be better, if poss, to alter dasd/cciss/etc and stop all these
s@/@!@everywhere games.




Isn't better to ask why there is a problem with the /'s? It would be
bad for Linux as a design to prevent passing arbitrary tail ends of
filenames off to arbitrary plugins of some kind. In general, in
namespace design, you want to allow delegating the job of
resolving/interpreting the tail end of a file that the front end has
identified as something that can interpret it.

Forgive me, I probably understand something wongly about procfs and this
issue....
