Due to commit 996a2493ed5d3a8d5db03b560fcbbf1ca3f10897 (NFS:
Use i_writecount to control whether to get an fscache cookie in
nfs_open(), in two instances a local variable is only used in debug
print statements. Said statements might be compiled out, which results
in unused variable warnings:
fs/nfs/fscache.c: In function 'nfs_fscache_release_page':
fs/nfs/fscache.c:263:21: warning: unused variable 'nfsi' [-Wunused-variable]
fs/nfs/fscache.c: In function '__nfs_fscache_invalidate_page':
fs/nfs/fscache.c:286:20: warning: unused variable 'nfsi' [-Wunused-variable]
Just skip the local variable in these cases.

David,
This showed up in today's linux-next, seems to have come in through the fscache tree.
Either amend and roll in the fix (after review -- I'm guessing this is the right thing to do), or apply on top please. :)
Thanks!
