Hi Adrian

With your patch, grub now fails to build as follows:

fs/f2fs.c: In function 'grub_f2fs_get_block':
fs/f2fs.c:864:43: error: 'offset' may be used uninitialized in this
function [-Werror=maybe-uninitialized]
  864 |     return grub_le_to_cpu32 (inode->i_addr[offset[0]]);
      |                                           ^
cc1: all warnings being treated as errors
make[4]: *** [Makefile:33773: fs/f2fs_module-f2fs.o] Error 1

This is the last 1000 lines of the build log with your patch applied:
http://ix.io/1IfE

And this is the f2fs.c used for the compilation (it includes your
patch): http://ix.io/1IfC

Many thanks
Neil
