Every system I've seen has the /build symlink but not the /source symlink.
Simplified module to use sysfs instead of debugfs
Instead of coping with the debugfs the module now declares two
read only module parameters -- read and call. They appear in
sysfs under /sys/module/nullderef/parameters.
Oops, spurious "q"
Some small README fixes.
Remove the local 'struct dentry's.
These were accidentally left in in the previous commit.
Don't use debugfs_remove_recursive.
It doesn't exist on older kernels.
