[GIT PULL] fscache, cachefiles: Miscellaneous fixes

[David Howells]

Hi Linus,

Here's a collection of fixes for fscache and cachefiles, if you could pull
them:

 (1) Fix kdoc on fscache_use/unuse_cookie().

 (2) Fix the error returned by cachefiles_ondemand_copen() from an upcall
     result.

 (3) Fix the distribution of requests in on-demand mode in cachefiles to be
     fairer by cycling through them rather than picking the one with the
     lowest ID each time (IDs being reused).

David
