Linux Kernel 2.6.15.4 has been released
Changelog:Linux Kernel 2.6.15.4
md: remove slashes from disk names when creation dev names in sysfs
e.g. The sx8 driver uses names like sx8/0.
This would make a md component dev name like
/sys/block/md0/md/dev-sx8/0
which is not allowed. So we change the '/' to '!' just like
fs/partitions/check.c(register_disk) does.
