[Linux-cachefs] FS-Cache for root only??

[Eli Stair]

Yes, it's not just you :)

Haven't had a chance to look back at this for a few weeks, but it is 
occuring in all my testcases.  I haven't had a chance to track it down 
at all, but the good news is systems have been running fully without any 
other errors caused by this for weeks.  At least it does caching for the 
root/system, and is verifiable in that regard.

Cheers,
