Re: [PATCH v2] fscache: fix OOB Read in __fscache_acquire_volume

[David Howells]

I think that the size needs to be able to hold up to 255 to handle NFS keys,
so I think the right solution has to be to fix the maths.  Probably the
easiest way is to change fscache_volume::key to be "u8 *" since it
isn't a simple text string.
