Attached are another couple of miscellaneous bits in FS-Cache and
CacheFiles:

 (1) Fix an uninitialised error value.

 (2) In MAINTAINERS, mark the mailing list as being moderated for
     non-subscribers.

fs/cachefiles/rdwr.c: In function ‘cachefiles_write_page’:
fs/cachefiles/rdwr.c:882: warning: ‘ret’ may be used uninitialized in
this function

If the jump to label "error" is taken, "ret" will indeed be
uninitialized, and random stack data may be printed by the debug code.

Fixes: 102f4d900c9c8f5e ("FS-Cache: Handle a write to the page immediately beyond the EOF marker")
