[PATCH 1/3] SLOW_WORK: Fix CIFS to pass THIS_MODULE to slow_work_register_user()

[David Howells]

As of the patch:

SLOW_WORK: Wait for outstanding work items belonging to a module to clear

Wait for outstanding slow work items belonging to a module to clear
when unregistering that module as a user of the facility. This
prevents the put_ref code of a work item from being taken away before
it returns.

slow_work_register_user() takes a module pointer as an argument. CIFS must now
pass THIS_MODULE as that argument, lest the following error be observed:

fs/cifs/cifsfs.c: In function 'init_cifs':
fs/cifs/cifsfs.c:1040: error: too few arguments to function 'slow_work_register_user'

Provide nop fscache_stat_d() macro if CONFIG_FSCACHE_STATS=n lest errors like
the following occur:

fs/fscache/cache.c: In function 'fscache_withdraw_cache':
fs/fscache/cache.c:386: error: implicit declaration of function 'fscache_stat_d'
fs/fscache/cache.c:386: error: 'fscache_n_cop_sync_cache' undeclared (first use in this function)
fs/fscache/cache.c:386: error: (Each undeclared identifier is reported only once
fs/fscache/cache.c:386: error: for each function it appears in.)
fs/fscache/cache.c:392: error: 'fscache_n_cop_dissociate_pages' undeclared (first use in this function)
