Please move this patch to the beginning of the series and replace
the commit log with something like the one below. Note that your
commit id is different from the one that will appear once applied

f2fs: use generic_file_llseek

f2fs always passes inode->i_sb->s_maxbytes to generic_file_llseek_size,
and thus should simply use generic_file_llseek. For now this is a just
a cleanup, but it will allow f2fs to pick up a race fix in
generic_file_llseek for free.
