Subject: [PATCH 0/2] fix a bug in ext2_max_size

When mkfs.ext2 with '-b 65536' and mount(arm 64KB page size),
function mount_fs will trigger WARNNING since ext2_max_size will
return value less than 0. Also, we cannot write any file in this
fs since the sb->maxbytes is less than 0.

Fix it by get the exact max file size.

yangerkun (2):
  ext2: remove static of ext2_block_to_path
  ext2: get the exact max filesize in ext2_max_size
