These messages are a regression compared with 2.6.24, which did not
flood the syslog with them.
The actual underlying problem was introduced in 2.6.23, when somebody
made the string parsing no longer accept nul-terminated strings as a
valid input to store_uevent().
Eg. "add\0" was valid prior to 2.6.23, where the code regressed to
require "add" without the '\0'.
This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code
once again tolerate the trailing '\0', if present.
According to GregKH, this mainly affects older Ubuntu systems, such as
the one I have here that requires this fix.
