[PATCH net-next 0/3] fscache: quick review

[David Howells]

Hi Anna, Steve,

Could you give these three patches a quick look over?  They:

 (1) Modify the netfs->fscache API to store the index key, auxiliary data
     and data size in the cookie/object rather than calling back into the
     netfs - which reduces issues around making sure the netfs still
     exists.

 (2) Keep a list of all the cookies known to weed out duplicate cookies at
     the top.

I'd ideally like to try getting them into this merge window.

The patches can also be found on this branch on top of some other patches
which add a few fixes and some tracepoints:

Thanks,
David
