The name is wrong. "debugfs_create_fault_attr" refers to some function
exported by the debugfs code. But this function is exported by the
fault injection code.
I edited the patch and renamed it to fault_create_debugfs_attr, which
may not make a ton of sense - please let me know if there's something
more appropriate.
I suggest that all symbols exported by this system should start with
"fault_". ("fault_injection_" would be more appropriate, but it's
rather lengthy). Please take a look through the code, see if there's
anything else we should clean up.
