Merge tag 'fscache-next-20180406' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull fscache updates from David Howells:
"Three patches that fix some of AFS's usage of fscache:

(1) Need to invalidate the cache if a foreign data change is detected
on the server.

(2) Move the vnode ID uniquifier (equivalent to i_generation) from
the auxiliary data to the index key to prevent a race between
file delete and a subsequent file create seeing the same index
key.

(3) Need to retire cookies that correspond to files that we think got
deleted on the server.

Four patches to fix some things in fscache and cachefiles:

(4) Fix a couple of checker warnings.

(5) Correctly indicate to the end-of-operation callback whether an
operation completed or was cancelled.

(6) Add a check for multiple cookie relinquishment.

(7) Fix a path through the asynchronous write that doesn't wake up a
waiter for a page if the cache decides not to write that page,
but discards it instead.

A couple of patches to add tracepoints to fscache and cachefiles:

(8) Add tracepoints for cookie operators, object state machine
execution, cachefiles object management and cachefiles VFS
operations.

(9) Add tracepoints for fscache operation management and page
wrangling.

And then three development patches:

(10) Attach the index key and auxiliary data to the cookie, pass this
information through various fscache-netfs API functions and get
rid of the callbacks to the netfs to get it.

This means that the cache can get at this information, even if
the netfs goes away. It also means that the cache can be lazy in
updating the coherency data.

(11) Pass the object data size through various fscache-netfs API
rather than calling back to the netfs for it, and store the value
in the object.

This makes it easier to correctly resize the object, as the size
is updated on writes to the cache, rather than calling back out
to the netfs.

(12) Maintain a catalogue of allocated cookies. This makes it possible
to catch cookie collision up front rather than down in the bowels
of the cache being run from a service thread from the object
state machine.

This will also make it possible in the future to reconnect to a
cookie that's not gone dead yet because it's waiting for
finalisation of the storage and also make it possible to bring
cookies online if the cache is added after the cookie has been
obtained"

fscache: Maintain a catalogue of allocated cookies

Maintain a catalogue of allocated cookies so that cookie collisions can be
handled properly. For the moment, this just involves printing a warning
and returning a NULL cookie to the caller of fscache_acquire_cookie(), but
in future it might make sense to wait for the old cookie to finish being
cleaned up.

This requires the cookie key to be stored attached to the cookie so that we
still have the key available if the netfs relinquishes the cookie. This is
done by an earlier patch.

The catalogue also renders redundant fscache_netfs_list (used for checking
for duplicates), so that can be removed.
