[patch] #include <linux/pagemap.h> in fs/partitions/check.h

[Adrian Bunk]

Hi Marcelo,

fs/partitions/check.h uses page_cache_release that is

  #define page_cache_release(x)   __free_page(x)

in linux/pagemap.h but check.h doesn't include this file. This resulted in
the following compile error:

You only think this is a free country. Like the US the UK spends a lot of
time explaining its a free country because its a police state.
