The overlayfs has started enforcing a maximum file size, but is missing
the header file that defines the PAGE_CACHE_SIZE constant in some
configurations.
fs/overlayfs/super.c: In function 'ovl_fill_super':
fs/overlayfs/super.c:939:29: error: 'PAGE_CACHE_SIZE' undeclared (first use in this function)

The patch that introduced this was marked for stable, so I'm marking this
the same way.

Hmm, it uses MAX_LFS_FILESIZE. MAX_LFS_FILESIZE is defined in
<linux/fs.h>, which doesn't include <linux/pagemap.h>.
<linux/pagemap.h> includes <linux/fs.h> however. So shouldn't
MAX_LFS_FILESIZE be defined in <linux/pagemap.h> instead?
Thanks,
Miklos
