[lustre-devel] Dead code cleanup

[Dmitriy Cherkasov]

Folks,

I've found one last #if 0 block in the code, but when attempting to investigate 
its origin I ran into a dead end.

The code in question [1] has not been touched since 2013 [2], and seems to 
originate from one big patch [3] with a non-public commit history. I found the 
relevant bugzilla entry [4], but no history beyond that.

Although I was unable to find the original intent behind it, I think it's safe 
to assume it is not used and if there are no objections I'll post a patch to 
remove it.

Thanks,
Dmitriy
